All in the Family is an American sitcom television series that aired on CBS for nine seasons from January 12, 1971, to April 8, 1979, with a total of 205 episodes. It was later produced as Archie Bunker's Place, a continuation series, which picked up where All in the Family ended and ran for four seasons through April 4, 1983.

Based on the British sitcom Till Death Us Do Part, All in the Family was produced by Norman Lear and Bud Yorkin. It starred Carroll O'Connor, Jean Stapleton, Sally Struthers, and Rob Reiner. The show revolves around the life of a working-class man and his family. It broke ground by introducing challenging and complex issues into mainstream network television comedy: racism, antisemitism, infidelity, homosexuality,^{[citation needed]} women's liberation, rape, religion, miscarriage, abortion, breast cancer, the Vietnam War, menopause, divorce, and impotence. The series became arguably one of television's most influential comedies, as it injected the sitcom format with more dramatic moments and realistic, topical conflicts.

All in the Family has been ranked as one of the best American television series. The show became the most watched show in the United States during summer reruns of the first season and topped the yearly Nielsen ratings from 1971 to 1976, the first television series to have held the position for five consecutive years.

All in the Family centers on a working-class White American family living in Queens, New York. Its patriarch, Archie Bunker (O'Connor), is an outspoken, narrow-minded man, seemingly prejudiced against everyone not like him or not holding his ideas of how people should be. Archie's wife, Edith (Jean Stapleton), is sweet and understanding, which can make her appear naive and uneducated. Her husband often treats her dismissively and uses disparaging language, calling her "dingbat."

Their one child, Gloria (Sally Struthers), is generally kind and good-natured like her mother but displays traces of her father's stubbornness and temper. Unlike them, she is a feminist. Gloria is married to college student, later graduate student, later college instructor Michael Stivic (Reiner)—referred to as "Meathead" by Archie—whose values are likewise influenced and shaped by the counterculture of the 1960s. The two couples represent the real-life clash of values between the Greatest Generation and Baby Boomers. For much of the series, the Stivics live in the Bunkers' home to save money, providing abundant opportunity for the family members to irritate one another.

The show is set in the Astoria section of Queens, with the vast majority of scenes taking place in the Bunkers' home at 704 Hauser Street. Occasional scenes take place in other locations, especially during later seasons, such as Kelsey's Bar, a neighborhood tavern that Archie spends a good deal of time at and eventually purchases, and the Stivics' home after Mike and Gloria move out.

Supporting characters represent the changing demographics of the neighborhood, especially the Jeffersons, a Black family, who live in the house next door in the early seasons and then leave the area for the higher-end Upper East Side of Manhattan after George (the husband) makes a fortune through his dry cleaning business. The Jeffersons then rented their home to Gloria and Mike.

Lear said the idea for All in the Family came to him after he read an article in Variety magazine on the successful British sitcom Till Death Us Do Part. He said he immediately knew it portrayed a relationship just like the one between his father and himself. However, in a 2025 episode of the podcast Let's Talk About That!, Struthers disputed that claim, saying that idea originated with O'Connor, who had seen Till Death Us Do Part during a visit to the U.K. O'Connor, she said, wanted to produce an American version but couldn't get the necessary backing as an actor alone. Eventually he got the idea to Lear who backed it and put it into production without crediting O'Connor. She said she waited until after Lear died to share what she knew.
