Your Show of Shows was a live 90-minute sketch comedy television series appearing weekly in the United States on NBC, from February 25, 1950 until June 5, 1954, featuring Sid Caesar and Imogene Coca. Other featured performers were Carl Reiner, Howard Morris, Nanette Fabray, Bill Hayes, Judy Johnson, The Hamilton Trio and the soprano Marguerite Piazza. José Ferrer made several guest appearances on the show.

The show was created by Sylvester Weaver and directed by Max Liebman. Writers for the show included Mel Brooks, Neil Simon, Danny Simon, Larry Gelbart, Mel Tolkin, and Carl Reiner who, though a cast member, always sat in with the writers. A common misconception is that Woody Allen wrote for Your Show of Shows; he in fact wrote for its successor program, Caesar's Hour, which ran from 1954 to 1957. Caesar, Coca, and Liebman had worked on The Admiral Broadway Revue from January to June 1949.

Carl Reiner has stated that the time he spent on Your Show of Shows was the inspiration for The Dick Van Dyke Show. Your Show of Shows also inspired the 1982 film My Favorite Year, produced by Mel Brooks, and the play Laughter on the 23rd Floor written by Neil Simon.
