All in the Family is an American television sitcom that aired on CBS for nine seasons, from January 12, 1971, to April 8, 1979. Afterwards, it was produced as the continuation series Archie Bunker's Place, which picked up where All in the Family had ended and ran for four more seasons through 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. The show broke ground in its depiction of issues previously considered unsuitable for a US network television comedy, such as racism, antisemitism, infidelity, homosexuality, women's liberation, rape, religion, miscarriages, abortion, breast cancer, the Vietnam War, menopause, and impotence. Through depicting these controversial issues, the series became arguably one of television's most influential comedic programs, as it injected the sitcom format with more dramatic moments and realistic, topical conflicts.

All in the Family is often regarded in the United States as one of the greatest television series in history. The show soon became the most watched show in the United States during the summer reruns of the first season, and afterwards ranked number one in the yearly Nielsen ratings from 1971 to 1976. It became the first television series to reach the milestone of having topped the Nielsen ratings for five consecutive years. The episode "Sammy's Visit" was ranked number 13 on TV Guide's 100 Greatest Episodes of All Time. TV Guide's 50 Greatest TV Shows of All Time ranked All in the Family as number four. Bravo also named the show's protagonist, Archie Bunker, TV's greatest character of all time. In 2013, the Writers Guild of America ranked All in the Family the fourth-best written TV series ever.
