Whose Line Is It Anyway? (abbreviated to Whose Line? or WLIIA) is a short-form improvisational comedy radio programme, which ran for six episodes on BBC Radio 4 in 1988. A television version of the show began on Channel 4 later that year, which ran for ten years. Following the conclusion of the British television show in 1998, ABC began airing an American television version, which lasted until 2007 before returning on The CW in 2013.

The show consisted of a panel of four performers who create characters, scenes and songs on the spot, in the style of short-form improvisation games, many taken from theatresports. Topics for the games were based on predetermined prompts from the host.
