Caesar's Hour is a live, hour-long American sketch comedy television program that aired on NBC from 1954 until 1957. The program starred, among others, Sid Caesar, Nanette Fabray, Carl Reiner, Howard Morris, Janet Blair and Milt Kamen, and featured a number of cameo roles by famous entertainers such as Joan Crawford and Peggy Lee.

Widely considered a continuation of Caesar's earlier program, Your Show of Shows, Caesar's Hour included most of the same writers and actors, with the notable addition of Larry Gelbart in the latter show. Nanette Fabray replaced Imogene Coca, who opted to star in her own TV series in 1954, The Imogene Coca Show. The writing staff of the show was reunited in 1996 for an event at the Writers Guild Theater in Los Angeles called Caesar's Hour Revisited, excerpts of which were broadcast on PBS under the title Caesar's Writers.

The full two-hour special was available on VHS as a pledge premium from PBS. It was released on DVD for the first time on December 12, 2011. The reunion featured Caesar with Mel Tolkin, Neil Simon, Danny Simon, Mel Brooks, Carl Reiner, Larry Gelbart, Sheldon Keller, Aaron Ruben, and Gary Belkin. The moderator and researcher was Bob Claster.
