A situation comedy, or sitcom, is a genre of comedy centered on a fixed set of characters who carry over from episode to episode. Sitcoms can be contrasted with sketch comedy, where a troupe may use new characters in each sketch, and stand-up comedy, where a comedian tells jokes and stories to an audience. Sitcoms originated in radio, but today are found mostly on television as one of its dominant narrative forms. This form can also include mockumentaries.

A situation comedy television program may be recorded in front of a studio audience, depending on the program's production format. The effect of a live studio audience can be imitated or enhanced by the use of a laugh track.
