People's names in several cultures include one or more additional names placed between the first given name and the surname. Middle names could be either given names (like in Anthony Michael Hall) or surnames (like in George Walker Bush).
In Canada and the United States, such names are specifically referred to as middle name(s); in most European countries they would simply be regarded as second, third, etc. given names. In some countries there is usually only one middle name, and in the United States and Canada it is often abbreviated to the middle initial (e.g. James Ronald Bass becomes James R. Bass, which is usually standard for signatures) or omitted entirely in everyday use (e.g. just James Bass). In the United Kingdom he would usually be referred to either as James Bass, J. R. Bass or James Ronald Bass, or he may choose Ronald Bass, and informally there may be familiar shortenings. An individual may have more than one given name, or none. In some other countries, the term middle name is only used for names that are originally last names, but not part of the last name of the bearer (for instance one can have one's mother's maiden name as a middle name).
It is debatable how long middle names have existed in English speaking countries, but it is certain that among royalty and aristocracy the practice existed by the late 17th century (and possibly much earlier), as exemplified in the name of the Stuart pretender James Francis Edward Stuart (1688–1766).
Despite their relatively long existence in North America, the phrase "middle name" was not recorded until 1835 in the periodical Harvardiana. Since 1905, "middle name" gained a figurative connotation meaning a notable or outstanding attribute of a person, as in the phrase "discretion is my middle name."
The use of multiple middle names has been somewhat impeded recently by the increased use of computer databases that occasionally allow for only a single middle name or more commonly a middle initial in storing personal records, effectively preventing people with multiple middle names from being listed in such databases under their full name. Especially in the case of government records and other databases that are used for legal purposes, this phenomenon has sometimes been criticized[by whom?] as a form of discrimination against people who carry multiple middle names for cultural or religious reasons.
In the United States, the "middle initial or a religious initial" can be used to replace a middle name even if the name is not printed on a birth certificate. It is sometimes used in place of the middle name on identity documents, passports, driver licenses, social security cards, university diplomas, and other official documents. Examples of this form include George W. Bush and John D. Rockefeller. The abbreviation "NMN" (no middle name) or "NMI" (no middle initial) is sometimes used in formal documents where a middle initial or name is expected when the person does not have one. It is also common for people to use their middle name as the first name.
English-speaking countries 
Middle names are normally chosen by parents at the same time as the first name. Names that are popular as first names are also popular as middle names. The given name of a relative is often used because of tradition or to show esteem. A middle name may be chosen which might have been a social burden to the child as a first name, perhaps because it is unusual or indicates a particular cultural background. Surnames are also sometimes used as middle names, usually to honor a relative. A child is sometimes given a middle name that is the first or middle name of one of his or her parents. In the United States, it is also common for a baby boy to be given the same given name as his father, in which case the middle name may be used as if a first name so as to distinguish him from his father. A similar, but rarer, practice is for children to have their mother's maiden name as their middle name. So, Harriet, daughter of John Walker and Laura Walker née Marsay, would be called Harriet Marsay Walker. The practice is quite popular in the Southern U.S..
A minority use their middle names and, as with many minorities, suffer some intended or unintended discrimination. For example, many forms in the United States ask for first name and middle initial, when people who prefer their middle name may wish to be known either with a first initial (like J. Edgar Hoover), their full name (like John Fitzgerald Kennedy) or simply without the first name at all (Mitt Romney or Paul McCartney). People who choose to be known primarily by their middle name may abbreviate their first name to an initial (e.g. F. Scott Fitzgerald and W. Somerset Maugham). Rarely, individuals may be given only initials as middle names, with the initial(s) not explicitly standing for anything (e.g. Harry S. Truman). This practice is common among the Amish, who commonly use the first letter of the mother's maiden name as a solitary initial for the sons and daughters. Thus, the children of a woman named Sarah Miller would use the middle initial M. The practice of abbreviating middle names to initials is rare in the United Kingdom.
Examples of multiple middle names: Elizabeth Alexandra Mary (Queen Elizabeth II; as a queen, she does not use a surname), J. R. R. Tolkien, George H. W. Bush and V. V. S. Laxman. The British upper classes are traditionally fond of giving multiple middle names, deriving from the German aristocracy's predilection for this, for the obvious reason that the British Royal Family is now of German origin: for example, Prince William (William Arthur Philip Louis), Prince Harry (Henry Charles Albert David), The Princess Royal (Anne Elizabeth Alice Louise), and Prince Charles (Charles Philip Arthur George; flubbed by Diana during their wedding as “Philip Charles Arthur George”). In even more extreme examples, British musician Brian Eno's full name is Brian Peter George St. Jean le Baptiste de la Salle Eno; Canadian actors Donald Sutherland and Shirley Douglas named their son Kiefer William Frederick Dempsey George Rufus Sutherland. Often, middle names are names of famous and influential people throughout history, such as well-known baseball pitcher Cal McLish, whose full name is Calvin Coolidge Julius Caesar Tuskahoma McLish.

Spain and Hispanic America 
In Spain and Spanish America the traditional composition of personal names is different. In the name Juan Pedro Gómez Martínez, Juan Pedro are the given names, Gómez is the father's surname, and Martínez the mother's surname. Argentina is largely an exception, as most Argentinians' identity is recorded at birth using only the father's surname.
Many people have two given names (Juan Pablo, María Claudia) but use only one. In the case of women whose first name is María, it is not uncommon for the second name to be used alone. Other names, however, are considered as a unit, and often used together. Examples are José Luis and Juan Carlos. People with those names will tend to use both names together, rather than only the first name José or Juan. In some cases, people use nicknames that include part of both names (Marijose for María José, Juanjo for Juan José), but this is usually informal.
Traditionally, a person's surname is compounded by the father's surname (originally the paternal grandfather's last name) and the mother's last name (originally the maternal grandfather's last name). The first surname, that of the father, is the main one, but people commonly use both, making it easier to tell the father from the son, something harder to do in the US if both share the same first name. The son of Juan Carlos Pérez Larios and Susana Estela Ríos Domínguez, if given the same first name as his father, would be Juan Carlos Pérez Ríos. Pérez is the "important" last name and the one used if only one is needed. Another example is the father-and-son Puerto Rican baseball players known in English as Sandy Alomar, Sr. and Sandy Alomar, Jr.. In Spanish, their names are respectively Santos Alomar Conde and Santos Alomar Velázquez. Those so named may encounter difficulties in English-speaking countries with the way they are addressed in letters and formal documents. Since it is usual in these nations to have only one surname, it is assumed that the last word in a person's name is the surname, hence Gabriel García Márquez becomes Gabriel Marquez: a name they could not identify with. Legal documents based on passports or similar identification are a common source of this problem.
Portugal and Brazil 
Portugal and Brazil, as Portuguese-speaking countries, use Portuguese naming customs, in which the order of multiple family names is usually reversed from that of Spanish—with the mother's maiden name preceding the father's surname.
Complete names are formed generally as in Western Europe, i.e., by first names, followed optionally by one or more middle names, followed by the mother's family surname, followed by the father's family surname. However, it is quite common for a person to go by one of their surnames which is not the last one in order, especially if it very common. For example, someone called João Cavaco Oliveira can be commonly called "Cavaco" and Ayrton Senna da Silva chose to be known just as Ayrton Senna because Silva is a very common surname.
Arabs in parts of the Middle East, particularly the Levant, will generally have two middle names: their father's given name, followed by their grandfather's given name. Occasionally, Arabs living in Western countries or people of Arab ancestry will continue this practice.
Iran and Syria 
Iranians and some Arabs, particularly Syrians, customarily place another name before the given name. While not appearing in the middle of the full name, this prefixed name serves the same function as western middle names. This name is often given as a blessing, and are names by which the person would be normally addressed. The name "Mohammad" is one such frequently used name. For example, such a person might be named Mohammad Ali, Muhammad Hadi, or Mohammed Basheer, where Ali, Hadi and Basheer are the given name.

Males in some predominantly Catholic communities (Belgian, French, Irish, Italian, Spanish, Portuguese, German and Polish Catholics) are sometimes given what would otherwise be considered a female given name, especially the name Marie or Maria (famous examples being Erich Maria Remarque and Rainer Maria Rilke), In France, the most common case is to give a compound first name, such as Jean-Marie or, more rarely, André-Marie or Bernard-Marie; more rarely, Marie is used as third or subsequent given name. Females, too, are often given compound names which feature male given names, i.e. Marie-Pierre, or Marie-Georges. See French names for more details on naming practices in France.
Hispanic females, conversely, sometimes have the middle name José. This is particularly common in Roman Catholic families. Therefore, the name "María José" is a common female name, while "José María" is a common male name, such as with PGA Tour golfer José María Olazábal.
The use of such names is primarily a cultural issue, rather than a religious issue. There is no Church teaching regarding such names.
In many English-speaking countries it is customary for a person being confirmed in the Roman Catholic Church to adopt a Confirmation name, that may be used as a second middle name, and is without effect in civil law, unless, of course, the confirmand pursues the appropriate legal avenues.
In Malta, a person is given a first name, which is used in official documents. This name would be also the name given at baptism. Custom has it that that one has two godparents, and these choose a name each. These names are generally not officialised, but are recognised by the Church. These are then used as middle names. For example if the parents choose Noel as a first name, and the godparents choose David and Luke, the surname being Dimech, the child is named Noel David Luke Dimech. A common choice for godparent names used to be the name of an important person such as an ancestor, great grandparents, etc. However, often these names are not used by their holders and are referred to only if another person has the same first and last name, e.g. Noel D. Dimech.

Middle names do not traditionally exist for the Chinese people. Most Chinese names consist of three characters – the surname, followed by a two-character given name (ming), which is not separated into a first and middle name in usage. Some Chinese given names contain only one syllable (e.g. Wong Kit). In some cases, two-character given names follow a naming tradition in which the first character of the given name (and thus the second character in the three-character full name) indicates the person's generation in his/her family. For example, Emperor Yongzheng of Qing Dynasty has the given name Yin-zhen (胤禛) while his brothers' names all begin with the character "Yin" 胤. His sons' and nephews' given names all begin with the character Hong (弘). Traditionally, the list of generational names may be decided many generations in advance by the ancestors. In such naming systems, the de facto given name is the last character of a person's full name. Even if that was the case most of the time, sometimes the person's given name is the middle character and not the last. The one that's common in all the names of a generation of children of the same gender determines the "generation name".
A fading Chinese tradition is to use a style name, or courtesy name, called zì (字) in place of a male's given name in adulthood. Traditionally zì is given by one's father upon reaching the age of maturity at 20 years old. This name is intended for use in formal situations and formal writing and confers a status of adulthood and respect. Like the ming, the zì is composed of two characters which usually reflect the meaning of the ming. Prior to the 20th century, sinicized Koreans, Vietnamese, and Japanese were also referred to by their zì. An alternative courtesy name is the hào (simplified Chinese: 号; traditional Chinese: 號; pinyin: hào; Japanese gō; Korean: ho; Vietnamese: hiệu), which usually referred to as the pseudonym. A hào was usually self-chosen and it was possible to have more than one. It had no connection with the bearer's míng or zì; rather it was often a personal choice and may have reflected a personal belief or philosophy. Chinese adults may more frequently use the hào to refer to themselves. The zì or hào can be used independently of the given name and of each other, but the given name is almost always used with the last name in official situations.
Some Chinese Americans move their Chinese given name (transliterated into the Latin alphabet) to the middle name position and use an English first name, e.g. James Chu-yu Soong, Jerry Chih-Yuan Yang, and Michelle Wingshan Kwan. The Chinese given name usually has two characters which are usually combined into a single middle name for better organizational purposes, especially with Cantonese names, such as Bruce Lee's middle name, Junfan. There are also some new immigrants whose Chinese given names are their first names followed by English middle names.
The practice of taking English and Chinese given names is also common in Malaysia, Singapore, Hong Kong, and Taiwan. However, rather than placing the Chinese given name between the English given name and the family name, it is commonly placed after the family name in these places. Under such a system, Bruce Junfan Lee would have been Bruce Lee Junfan. This practice is consistent with both the Western convention of putting the given name before the family name and the Chinese convention of putting the given name after the family name.
German speaking countries 
Legally, a person has one or several given names (forenames) and one surname. Using the mother's maiden name as a given name is generally not admissible unless it happens to be a name that is accepted as a first name; using a parent's first name as the child's middle name is allowed, but uncommon. In the case of multiple given names, the individual (or parents) will choose which name to use on a daily basis, as all of these names are legally equivalent. For example, the German Chancellor Angela Dorothea Merkel could decide to be called Angela Merkel, Dorothea Merkel, or Angela Dorothea Merkel. Hyphenated names, however, count as one item. Someone called Hans-Jürgen, for instance, cannot choose to drop either part of his given name. Initials are not commonly used to abbreviate extra given names. One prominent exception is German TV personality Johannes B. Kerner with the 'B' standing for 'Baptist'.
There are very few unisex names. An exception is the use of Maria for males (among Catholics), but not as a first given name; so Rainer Maria Rilke would be admissible, but Maria Rainer Rilke would not be. If one of the forenames happens to be unisex (e.g. Robin or Toni), at least one additional, unambiguous name must be chosen. Furthermore, parents can neither choose names likely to expose the child to ridicule nor those that would normally be assumed to be surnames. Foreign names are generally admissible if the parents can prove that the name is actually in regular use somewhere in the world.
Modern Germany 
As a modern attitude of gender neutrality, the German law on marriage names (Namensrecht: Ehename) chosen as surnames was changed to allow for free choice between mother's name or father's name. Only that individual of a couple that changes her/his name is allowed to include her/his name of birth (for women: 'maiden name') as a middle name. This actual state of the law was preceded by an intermediate version stipulating just the opposite order. By administratively set by-law and without prior explicit legislative process, and different from most international habits, the German authorities force to separate both parts of the surname with a dash Allgemeine Verwaltungsvorschrift. However, a dash is not applied between parts of traditional names.
Nazi Germany 
Beginning in 1938, specific middle names were imposed on many German Jews by the Nazi government to mark them as "non-Aryans" according to the racist ideology of the party. This antisemitic measure applied to all Jews who did not have a first name that was on a list of supposedly "typically Jewish" names drawn up by the government, as many German Jews at that time bore first names that were no different from those used by other Germans. The names forced upon them were Israel for males and Sara for females, both of them extremely rare among non-Jewish Germans at that time. Failing to use these imposed names in any kind of official communication was punishable. Also for any Jews born in Nazi Germany from that time, the parents were forced to choose only names from the above mentioned government list of "Jewish names". This discriminating code of practice had been formally amended as a by-law (Runderlass des RMI vom 23. August 1938, printed in: Stefan Petzhold: Juden in Bergedorf / Schlossheft Nr. 8, hrsg. Verein der Freunde des Museums für Bergedorf und Vierlande, Hamburg, o.J., p.33) to the German Civil Code and was terminated after capitulation of 1945, May 7th and under allied military government thereafter. Author of the Runderlass was the former Nazi constitutional lawyer Hans Globke, later Ministerialdirigent in the office of the chancellor Konrad Adenauer.
In Switzerland, for several unisex first given names like Andrea (female in German, male in Italian) or Maria, a second given name is required. A third given is required for given names like Andrea Maria.
Legally, a person has one or several given names and one surname. In the case of multiple given names, the individual (or parents) will choose which name (or a derivative thereof) to use on a daily basis ("roepnaam"), as all of these names are given the same "rank". For the most part the naming convention is similar to Germany. In the Netherlands, and also in Belgium, many surnames include a tussenvoegsel: a prefix such as "van der". Many Dutch databases have a separate field to store the tussenvoegsel. In a Dutch phone directory you would find Edwin van der Sar under S for Sar, instead of under V. This is not the case in Belgium, however.
In Denmark and Norway, the term middle name refers to names that are originally surnames, but not part of the last name of the name bearer. A middle name could be e.g. one's mother's maiden name or the last name of another recent ancestor (for instance a grandparent). One can have several middle names, but it is unusual to have more than one or two. In law, middle names have a separate status. In practice, their status is similar to that of additional given names, and middle names are often omitted in everyday use, just like a person with 3 or 4 given names would only use one of them in most situations. The historical purpose of middle names is to honour some related family or person. Until the 19th century, it was not unusual to have the last name of a godparent as one's middle name, even when the godparent was no blood relative. This practice, and the use of middle names in general, however, was mostly limited to the bourgeois class and the nobility, and was seldom seen among common people. In the 20th century, the use of middle names, especially one's mother's maiden name, was more widely adopted, although it is by no means mandatory. There are few set rules for how names are constructed today; people are required to have one given name and one family name, but can have as many additional given names and middle names as they like.
In the example Carl Viggo Manthey Lange, the names Carl and Viggo are given names, while Manthey is a middle name and Lange is the family name. Manthey is his mother's maiden name. Unless his full name is used, he is correctly referred to as Mr. Lange, not as Mr. Manthey Lange. Carl Viggo Manthey Lange has a name typical of the Norwegian bourgeois class, with both his family name and his middle name being of foreign origin and being recognised surnames. Most Norwegians and Danes of the working class and peasant class used patronymics until the 19th century, when permanent family names became mandatory, first in Denmark in the early 19th century and then in Norway around 1900. A middle name is usually a recognised surname and not a patronymic. One reason middle names have become popular in the 20th century, particularly in Denmark, is that most Danish surnames originated as patronymics and are shared by a large number of people. The use of middle names in modern times serves to differentiate them from other people. For example, Danish politician Lars Løkke Rasmussen has some of the most common given and last names in Denmark (Lars and Rasmussen); his mother's maiden name is the slightly more unusual name Løkke, derived from a small agricultural property, so he uses it as a middle name, which differentiates him from other people named Lars Rasmussen.
In Sweden, the position is much the same as in Denmark. Middle names were inaugurated in the previous Name Act of 1963, then called "tilläggsnamn" (additional name), and are called "mellannamn" (middle name) as of the present Name Act of 1983. However, it had previously been more common to join e.g. the last names of a child's both parents, or for a married woman to join her maiden name and the husband's last name, as a double name with a hyphen, and commonly, large portions of the Swedes have not adapted to the official system to this day, i.e. for almost 50 years. People often use a hyphen between their middle name and last name themselves, and/or are spelled that way by other people. Not even mass media know things correctly, but contribute to misinterpretations.
Furthermore, when the term middle name was introduced in Swedish ("mellannamn") the word was assumed by many to mean the additional given names (apart from the "name of address" (tilltalsnamn)), so since 1983 the word is being used more and more in this, officially, erratic meaning.
Occasionally, Scandinavians choose to use their middle name as their surname in everyday life. So Per Gottfrid Svartholm Warg has Per and Gottfrid as his given names, where Gottfrid, not Per, is his name of address, Svartholm as his middle name and Warg as his last name, but in practice he uses Svartholm as a surname. This usage, however, is unofficial. Historically, a middle name could become part of a double-barreled surname (family name) and hence cease to be a middle name, especially if used for several generations. There are many family names of this kind, which contributes to the confusion about middle names that shall not be hyphenated. Some of these double-barreled surnames are combined with a hyphen, while others are not, so a double surname without a hyphen can sometimes be indistinguishable from a middle name followed by a family name.
In Scandinavia, there is no limit on how many given names one can have. Given names have never been referred to as middle names, apart from many in Sweden believing so, as mentioned above. The use of more than two given names is generally associated with the upper class. The first given name is not necessarily the name of address. For the sake of completeness, Swedish forms often ask people to fill in all their given names and to indicate which one is their "name of address" (tilltalsnamn).
In Finland one can have up to three given names, one of which can be officially registered as the main forename. Upon marriage the original family name can be taken as a personal last name that is written before the actual last name and separated by a hyphen.
Southeast Asia 
In the Philippines, the middle name is used exclusively to refer to the mother's maiden surname. For example, Juan Miguel Batumbakal de la Cruz considers Batumbakal, his mother's maiden surname, to be his middle name. In ancient pre-Hispanic Philippines the use of middle names was rare, as this was adopted from Spanish conventions. The older (and still used in legal contexts) method of writing it would be, Juan Miguel de la Cruz y Batumbakal, which is a reverse of the conventional Anglicised format.
In Thailand, middle names are not common. Thai people usually give a child a long first name, which usually has a meaning. Additionally, most Thai children are also given nicknames, which are usually one or two syllables. Thai people are generally known by their nicknames; public figures such as politicians and actors are often referred to by their first names. Surnames are only rarely used in everyday speech.
South Asian 
Sikh men, who for religious reasons are supposed to be named Singh as their surname, sometimes instead take Singh as their middle name, such as Mudhsuden Singh Panesar, better known as Monty Panesar. Sikh women, who for similar reasons normally take the surname Kaur, may instead take it as a middle name: a notable example is Parminder Kaur Nagra.
In South India, the first initial is frequently a family name assigned to every member of a particular family, and is usually in addition to the last name. It is carried by every member of the paternal family. For example, Yeduguri Sandinti Rajasekhara Reddy can be broken down into Yeduguri, the surname; Sandinti, the family name; Rajasekhara, the first name and Reddy, the caste name.
In Tamil Nadu, the first initial is normally the place of birth, and is followed by the middle name, i.e. father's and/or mother's name and then the first name of the individual and then finally the caste/community name. For example, Morappakkam Vedachalam Sivakumaran Pillai. Here, Sivakumaran is his first name; Morappakkam is the place where he was born; his father's name is Vedachalam; and his caste/community is called Pillai.
In the states of Gujarat and Maharashtra in India, the middle name is the father's or husband's first name, though some people, such as Sanjay Leela Bhansali, use their mother's name as a middle name.
East Slavic names 
||This section may not provide balanced geographical coverage on Slavic countries. (December 2010)||
The East Slavic naming system uses a patronymic name system in which the middle name, or patronymic, is based on the name of one's father or a male ancestor, while the first name is a given name and the last name is the family surname. In Russia, Belarus and Ukraine the patronymic is composed of the father's first name followed by the suffix "-ovich"; or if the name ends with a "y" or a vowel, then it would be "-evich". For example, if Vladislav Petrov had a son named Georgy, then the full name would be something like Georgy Vladislavovich Petrov. If Georgy Petrov had a son named Nikolai, then the son's full name would be Nikolai Georgyevich Petrov. For women, the suffix ends with "-ovna" and "-evna". So if Georgy Petrov had a sister, named Lyudmilla, her full name would be Lyudmilla Vladislavovna Petrova. If Georgy Petrov had a daughter the patronymic would be Georgyevna. Non-Slavic countries that were former Soviet states, such as Kazakhstan, Uzbekistan and Kyrgyzstan, also use this naming system. In Kyrgyzstan, Russian is the official language. In Ukraine, the patronymic ends with "-ovych" for males and "-ivna" for females. In Bulgaria, the naming system is similar, but the patronymic ends with "-ov" or "-ev" for men and "-ova" and "-eva" for women. In Russia, such names would end with "-ich" as explained above. Some Russian patronymics are transliterated in English as "-ovitch" or "-evitch", with a "t": e.g. the famous Russian arachnologist, Alexander Ivanovitch Petrunkevitch: his father's name is Ivan. The most formal way to address a person is by first name and patronymic, not by surname.
The patronymic system was also imposed on people of other descent, both in the Russian Empire (e.g. Adam Johann von Krusenstern is known in Russia as "Ivan Fyodorovich Kruzenshtern") and in the Soviet Union (with certain exceptions). The patronymic in such names is sometimes mistaken for a middle name, especially as it is often rendered with the middle initial (e.g. Vladimir V. Putin).
There are no formal conventions that forbid the first name from corresponding with the patronymic. A son named after a father is permissible and relatively common, making for names like Sergey Sergeyevich Ivanov. Although not a rule, the unwritten convention is to avoid giving children names that match their surname, so Sergey Ivanovich Sergeyev would be a less common name, and matching all three of first name, father's name, and surname is almost unheard of, thus a name such as Sergey Sergeyevich Sergeyev would most certainly be considered quaint.
Illegitimacy, adoption, and estrangement from the father are sometimes reasons for unconventionally formed patronymics. Unwed mothers who do not list the father on their children's birth certificates are commonly asked either to provide or to make up a male first name, to be used as the legal patronymic. Legally adopted stepchildren sometimes change their patronymics officially or informally use a non-legal patronymic occasionally or interchangeably. Adults may change their patronymic legally while keeping their first name and surname. This is often done to honor a stepfather or to distance oneself from an absent or disliked biological father; or to avoid an odd-sounding patronymic; or to erase one's visible connection to a different culture or ethnicity, perhaps to conform in order to avoid discrimination, or to sever a tie with a culture with which one does not identify. Foreign patronymics may also be Russianised, either legally or informally, for simplicity's sake (such as Andrew'vich → Andreyevich, or Andriyovych → Andreyevich).
