A serial killer is typically a person who murders three or more people, in two or more separate events over a period of time, for primarily psychological reasons. There are gaps of time between the killings, which may range from a few days to months, or many years. This list shows serial killers from the 20th century to present day by number of victims. In many cases, the exact number of victims assigned to a serial killer is not known, and even if that person is convicted of a few, there can be the possibility that they killed many more.
Organization and ranking of serial killings is made difficult by the complex nature of serial killers and incomplete knowledge of the full extent of many killers' crimes. To address this, multiple categories have been provided in order to more accurately describe the nature of certain serial murders. This is not a reflection of an individual's overall rank, which may or may not vary depending on personal opinion concerning the nature and circumstances of their crimes. The fourth column in the table states the number of victims definitely assigned to that particular serial killer, and thus the table is in order of that figure. The fifth column states the number of possible victims the killer could have murdered. Some of these crimes are unsolved, but were included because they are the work of a serial killer, despite nobody being caught.
Serial killers with the highest known victim count
The most prolific modern serial killer is Harold Shipman, with 218 proven murders and possibly as many as 250 (see "Medical professionals", below). Excluding these "Medical professionals and pseudo-medical professionals", with their ability to kill simply and in plain sight, and Serial killer groups and couples (below), this list is a compilation of modern serial killers currently with the highest verifiable murder count.

|Ivomoku Bakusuba||Burundi||1940s||67||Confessed to killing 67 children by strangling them with a bedsheet. Committed suicide, "probably in late 1940s or in early 1950s". As information on this serial killer was only revealed by a police officer in 2018 during a conversation with a Brazilian writer, and there is no information on his conviction, the confirmation that he was a serial killer is debatable.|
|Bruno Lüdke|| German Reich
|1928 to 1943||51||86||Mentally disabled, Lüdke was arrested after being discovered with a corpse. Police declared him insane and imprisoned him in a psychiatric hospital, where he died when he was experimented on. The only evidence tying him to the crimes was a confession that may have been physically coerced. He was never given a trial and he is generally[by whom?] considered innocent.|
|"Highway of Tears" Killer||Canada||1969 to 2018 ?||18||83||All the victims were young women and were last seen on Highway 16 in British Columbia between Prince George and Prince Rupert. If they were all victims of the same person, it would be one of the most proficient serial killers in Canada and one with the longest career in the world. Some of the murders have been linked to American criminal Bobby Jack Fowler, although he was in prison at the time others were committed.|
|Gerald Stano||United States||1969 to 1980||22+||41||Confessed to killing 41 women in mostly Florida and New Jersey areas. Some controversy surrounds the case as he is believed by some to have been a serial confessor.|
|Orlando Sabino||Brazil||1966 ? - 1971 ?||12||Suspected of murdering 12 people in Minas Gerais and Goiás, as well as mutilating several animals; sentenced to 38 years imprisonment and died from a heart attack in 2013. There are many theories that he was actually framed by the Military Dictatorship in Brazil, who did the murders for political reasons.|
|Pedro Rosa da Conceição||Brazil||1904 to 1911, ???||3||17||Brazilian mass murderer who killed three people and wounded thirteen others on April 22, 1904. Killed his cellmate and a guard in 1911, and is said to have murdered a family of twelve people in an unspecified date and year. Died in 1919. The family murders are not verified.|
|Henry Lee Lucas||United States||1960 to 1983||3||3000+||Confessed to killing at least 600 people but later recanted and is suspected of lying about a majority of the murders. He originally offered a list of 77 women from 19 different states, but as he confessed to more and more murders, the details became increasingly more bizarre. Some included dismemberment, necrophilia, even cannibalism. Lawmen linked Lucas and Ottis Toole to 81 murders only. Convicted of 11 murders. The true number of murders committed by Lucas is unknown, but it is likely Lucas was not nearly as prolific a serial killer as he initially claimed to be, as most of his murder confessions were thoroughly discredited, and he himself claimed only one murder—that of his mother.|
|Charles Quansah||Ghana||1993 to 2001||8||34||Quansah, who had been in prison for rape twice, was held as a suspect in the deaths of 34 women across the country, including his girlfriend who was strangled in 2000, and eventually confessed to eight murders. He later denied the killings, claiming that the confessions had been extracted under torture, and that the police had also tried unsuccessfully to force him to implicate a number of politicians including former president Jerry Rawlings, his wife Nana Konadu Agyeman and an unidentified member of president John Kufuor's administration.|
|Ottis Toole||United States||1980 to 1983||7||100–125||Initially convicted of three counts of murder, later pleading guilty to four more murders before dying in prison. A sometime accomplice of convicted serial killer Henry Lee Lucas, Toole admitted to—and retracted multiple times—over 100 counts of murder, rape, arson and cannibalism, and was the suspect in several other unsolved murders. In 2008, police announced that they had identified Toole as the likely murderer of Adam Walsh, and would be closing the case as a result.|
|Wayne Williams||United States||1979 to 1981||2||24–31||Believed to have perpetrated the Atlanta murders of 1979–1981. After being convicted of two murders and sentenced to life imprisonment, authorities closed 22 other unsolved murders, declaring Williams to have been the perpetrator. Williams has maintained his innocence and the case was reopened in 2005.|
|Joe Ball||United States||1937 to 1938||2||20||Bootlegger and barman known as the "Butcher of Elmendorf", the "Bluebeard of South Texas", and "the Alligator Man" because of the alligator pit he had in the back of his bar and where he entertained clients by throwing live animals to the reptiles. Ball killed two barmaids but he shot himself fatally in the chest when police came to question him and was never arrested or interrogated. Yellow press and pulp magazines later exaggerated his exploits, claiming that he had killed up to 20 women and fed them to the alligators, but this was never proven and caused some of Ball's relatives to sue such publications. Police investigated about a dozen women that had worked at Ball's place and were missing at the time of his suicide; some were found alive in San Antonio, but others could not be accounted for.|
|Abdul Latif Sharif||Mexico||1995||1||18–20||Egyptian chemist known as "The Jackal of Ciudad Juárez". After migrating to the United States in the 1970s, Sharif served 14 years in prison for several rapes but fled to Mexico when he was about to be deported to his home country. There, he was accused of up to 20 of the female homicides in Ciudad Juárez but was convicted of only one, to 30 years in prison, where he died of natural causes in 2006. As the high rate of female murders has continued to this day in Ciudad Juárez, it has been claimed that Sharif was used as a scapegoat by the Mexican police.|
|Daisuke Mori||Japan||2000 and earlier||1||11+||Nurse that was sentenced to life imprisonment for one murder but suspected of killing at least 10 others. He might have confessed to some of the murders in order to protect others.|
|Bevan Spencer von Einem||Australia||1979? to 1983||1||10||Arrested for three and convicted of one of "The Family Murders", where four teenagers and one young adult, all male, were drugged, kidnapped, raped and mutilated for several weeks before their bodies were abandoned in the countryside near Adelaide. Police believed that von Einem had several accomplices, none of whom was publicly identified or detained, and at the time of his trial it was widely reported that the murders had been committed by a group of four to 12 high-profile Australian men; von Einem himself claimed to be the victim of a conspiracy. He has also been considered a suspect in the disappearance of two girls near the Adelaide Oval in 1973 and the high-profile Beaumont children disappearance in 1966.|
|Edgar Matobato||Philippines||1988 to 2013||0||Hundreds||Self-confessed hitman and serial killer claiming to have killed people as part of the Davao Death Squad; his claims' authenticity has been challenged.|
|John Bodkin Adams||United Kingdom||1946 to 1956||0||163||Acquitted in a highly unusual trial in 1957 of murder but later found guilty of fraud. Archive evidence shows that he was almost certainly a killer but that his prosecution was sabotaged for political reasons.|
|The Man from the Train||United States||1898 to 1912||0||40–100+||Murdered entire families in their sleep, arriving and departing by train. Existence (and probable but not proven identity) discovered more than 100 years after the murders, by analysis of contemporary records, showing a markedly common modus operandi for many previously unconnected murders.|
|David Parker Ray||United States||1950 to 1999||0||60||Torture-murderer possibly aided by numerous accomplices, including his girlfriend. Targeted victims in the Truth or Consequences, New Mexico, area. Convicted of attempted killing of three victims and is suspected of 60 murders, even though no bodies were ever found. Known as the "Toybox Killer" for the self-built mobile home he used in the rape, torture, and killing of women.|
|Smiley Face Killer||United States||1990s to 2000s||0||40+||Theoretical serial killer(s) thought by some sources to have drowned college-aged young men across the northern part of the country since 1997; most experts suggest that the deaths were accidental.|
|Marie Besnard||France||1927 to 1949||0||13||Charged with the murders of 13 relatives with arsenic, all of whom had Besnard as their sole designated heir, but acquitted of all charges after three high-profile trials that lasted a decade.|

Serial murder is the killing of three or more people over a period of more than 30 days, with a significant cooling-off period between the murders [...] The baseline number of three victims appears to be most common among those who are the academic authorities in the field. The time frame also appears to be an agreed-upon component of the definition.
