Mitchell and Webb are a British comedy double act composed of David Mitchell and Robert Webb. They are best known for starring in the Channel 4 sitcom Peep Show and their radio and TV sketch shows That Mitchell and Webb Sound and That Mitchell and Webb Look. The duo first met at the Footlights in 1993 and collaborated on the 1995 revue while at Cambridge.

A double act is a form of comedy originating in the British music hall tradition, and American vaudeville, in which two comedians perform together as a single act, often highlighting differences in their characters' personalities. Pairings are typically long-term, in some cases for the artists' entire careers. Double acts perform on the stage, television and film.
