A seudat mitzvah (Hebrew: סעודת מצוה, "commanded meal"), in Judaism, is an obligatory festive meal, usually referring to the celebratory meal following the fulfillment of a mitzvah (commandment), such as a bar mitzvah, a wedding, a brit milah (ritual circumcision), or a siyum (completing a tractate of Talmud or Mishnah). Seudot fixed in the calendar (i.e., for holidays and fasts) are also considered seudot mitzvah, but many have their own, more commonly used, names.
Seudat Brit Milah 
Attendance at a brit milah (circumcision) and its subsequent seudah is of such great significance that Rabbi Moshe Isserles ("the Rama") notes (Yoreh De'ah 265:12) that one who is invited but does not participate in the seudat brit milah is excommunicated from Hashem (God). (Babylonian Talmud tractate Pesachim 113b; Tosafot Pesachim 114a s.v. "Veein"). For this reason, people are generally not invited, but merely informed of the brit's time and location (Pitchei Teshuva Y.D. 265:18; Arukh HaShulkhan 265:37). Talmudic sages have compared a brit to a Korban (Temple offering), and eating at a seudat brit milah to eating a Temple offering. Hasidic Jews generally insist on serving meat at a seudat brit milah since most Temple offerings were meat. Sharing a meal is considered a bonding experience celebrating the covenant between God and the Jewish people.
Seudat Pidyon HaBen 
Unlike other seudot mitzvah in which the meal (seudah) follows the act or ceremony which warrants the festive meal, the redemption ceremony for a first-born Jewish male child (called Pidyon HaBen in Hebrew), is actually part of the meal. The ceremony is led by a kohen, who ritually washes his hands, recites the blessing over bread, and partakes of some bread before beginning the ceremony. The ceremony, which follows a traditional text, is a verbal exchange between the kohen and the father of the child. The kohen asks the father if he prefers to keep his money, or pay the equivalent of five silver shekels to redeem his child. The father chooses the latter option and hands over the money, as well as recites a special blessing ("al pidyon haben"). Then the kohen verbalizes the redemption, blesses the child, and says the traditional blessing over a cup of wine, which he then drinks. The seudat mitzvah continues with all guests in attendance washing for bread and partaking of the festive meal.
While attending the seudah for a Pidyon Haben, the Vilna Gaon was asked whether it was true that all the Torah's commandments are alluded to in Bereishit, the first portion of the Torah. After the Gaon affirmed this, he was asked where the commandment of pidyon haben was alluded to and the Gaon replied that it was in the word Bereishit, the Hebrew initials which stand for Ben Rishon Achar Sheloshim Yom Tifdeh or "a firstborn son after thirty days redeem".
Seudat Bar Mitzvah 
Rabbi Shlomo Luria ("Maharshal") notes that the occasion of a youth becoming obligated to obey the commandments is to be celebrated with a religious feast, usually including a sermon the youth has prepared (Yam Shel Shlomo, Bava Kamma 7:37). It is customary at a bar mitzvah meal for parents to give thanks and praise to God for giving them the merit to raise a child to bar mitzvah and to educate him in the ways of Torah and the commandments. Rabbi Ovadiah Yosef holds that a Bat Mitzvah is also a seudat mitzvah.
Seudat Siyum Masechet 
Based on the Talmud and Midrash, the seudah celebration upon the completion of a Talmudic tractate is considered a seudat mitzvah (Yam Shel Shlomo, Bava Kamma, Merubah 37; Maharam Mintz 119; Shach, Yoreh De'ah 246:37). This seudah is made to rejoice over the accomplishment, and also to motivate and inspire others to do the same. Rabbi Chaim Elazar Shapiro (the "Munkatcher Rebbe") observes in his work Sha'ar Yissachar that the evil inclination does not want to see this type of shared joy, noting that one of the names of the evil inclination, "Sama'el," may be seen as an acronym for Siyum Masechet Ain La'asot, or "do not make a siyum".
Seudat Nissuin 
During the festive meal following a Jewish wedding ceremony (Hebrew Nissuin), guests participate in the mitzvah (commandment) of L'Sameach Chatan v'Kallah, to bring joy to the groom and bride. The emphasis of the celebration is on entertaining the newlyweds. At Orthodox wedding meals, men and women dance separately - sometimes separated by a divider - for reasons of modesty. At the end of the seudat nissuin, Grace After Meals is recited, and the Sheva Berachot (seven blessings) that were recited under the wedding canopy are repeated.
Seudat Havraah 
Seudat Havraah is the "meal of consolation" or comfort provided for a mourner upon his or her return from the cemetery following interment of the deceased. It usually consists of foods symbolic of life such as boiled eggs and lentil soup. The Talmud in Bava Batra (16b) states that the lentil stew Jacob was preparing (Genesis 25:29), and for which Esau sold his birthright, was the seudat havraah for his father Isaac who was beginning to sit shiva for his father Abraham.
Seudat Shabbat and Seudat Yom Tov 
These include three meals on the Sabbath, as well as two (dinner and lunch) on each festival day making four each (outside Israel) for Shavuot, Rosh HaShana, Sukkot, two each for Shemini Atzeret and Simchat Torah, eight (outside Israel) for Passover. The Passover Seders are seudot mitzvah. Except for Seudah Shlishit (the "third meal" of Shabbat) all of these meals are preceded by Kiddush (the blessing, made over wine, recognizing the holiness of the day). If one recites Kiddush, Jewish law states that one must immediately eat the seudah in the same place that he heard/recited Kiddush (Talmud Bavli, Pesachim 101a). At Shabbat meals, it is customary to sing Zemirot (songs), learn Torah (as at meals in general) and discuss the week's portion of Scripture.
Seudah HaMafseket 
At the pre-Tisha B'Av meal it is forbidden to eat meat (Mishna, Taanit 26b; Babylonian Talmud ibid. 30a), wine, and fish, or more than one cooked food. Alcoholic beverages should be avoided. The meal is eaten sitting on the ground or a low seat. It is customary to eat a hardboiled egg, and also a piece of bread dipped into ashes, and to say, "This is the Tisha B'Av meal." During the meal, three men should not sit together so they will not have to recite the Grace after Meals as a group. None of these restrictions apply when the eve of Tisha B'Av falls on the Sabbath.
The pre-Yom Kippur meal is a festive meal, which may include meat.
Seudat Purim 
On Purim day, typically toward evening, a festive meal called Seudat Purim is held, with wine as a prominent beverage. While Jews have long been noted for a lack of alcohol abuse, drunkenness is not uncommon at this meal. The jovial character of this feast is illustrated in the saying of the Talmud (Megilla 7b) stating that one should drink on Purim until he can no longer distinguish between the phrases, arur Haman ("Cursed is Haman") and baruch Mordechai ("Blessed is Mordechai"). (In Hebrew these phrases have the same numerical value, and some authorities, including the Be'er Hagolah and Magen Avraham, have ruled that one should drink wine until he is unable to calculate these numerical values.)
This saying was codified in the Rif, Rosh, Tur, Shulchan Aruch (Orach Chayim 695), and is interpreted simply (as explained above) by the Chatam Sofer. This interpretation of the Talmudic statement, or the acceptance of the statement itself, is disputed (for various reasons) by the Ba'alei Tosafot (based on the Jerusalem Talmud), Maimonides, Rabbeinu Ephraim, Ba'al HaMa'or, Ran, Orchot Chaim, Be'er Hagolah, Magen Avraham, Taz, Rema, Vilna Gaon, Maharsha, Rashash, Tzeidah LaDerech, Hagahot Maimoniyot, Ra'avyah, Korban N'tan'el, Bach, Maharil, P'ri M'gadim, Kol Bo, Chochmat Mano'ach, Mishnah Berurah (by the Chafetz Chaim), and others. These authorities all advocate drinking wine in some quantity, but all (excepting Hagahot Maimoniyot and Ra'avyah) discourage the level of drunkenness suggested by the Chatam Sofer. The Rema says that one should only drink a little more than he is used to drinking, and then try to fall asleep (whereupon he certainly will not be able to tell the difference between the two phrases indicated by the Talmud). This position is shared by the Kol Bo and Mishnah Berurah, and is similar to that of Maimonides.
