List of Whose Line Is It Anyway? (British TV series) episodes

Whose Line is it Anyway? (often known as simply Whose Line? or WLIIA) is a British improvisational comedy series hosted by Clive Anderson on Channel 4 which ran from 23 September 1988 to 4 February 1999. The programme ran for 10 series with 136 episodes in total, including the original 1988 pilot episode (broadcast as part of series 1), a 1989 Christmas special (broadcast as part of series 2), and 1 or 2 compilation episodes in each series, made up of materiel left out of that series' regular episodes.

The show consists 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 are based on either audience suggestions or predetermined prompts from the host. The show ostensibly take the form of a game show with Anderson arbitrarily assigning points and likewise choosing a winner at the end of each episode. However, the show lacks the true stakes and competition of a game show by design. The "game show" format is simply part of the comedy.

Most episodes were filmed in Britain, with several episodes in 1991 and 1992 filmed in New York and the entire last series filmed in Hollywood in 1998, coinsiding with the filming of the first series of the subsequent American version of Whose Line Is It Anyway?, which featured several of the same cast members as the British show.
