Three-sided football is a situationist game meant to disrupt one's everyday idea of football. A variant of another situationist game, two-sided football, it was devised by the Danish Situationist Asger Jorn. Played on a hexagonal pitch, the game can be adapted for similarity to soccer as well as other versions of football.

It has been promoted in England, Scotland, Italy and Austria by the Luther Blissett Three-sided Football League. The first known game played was organized by the London Psychogeographic Association at the Glasgow Anarchist Summer School in 1993.

The Haxey Hood Game is a traditional football game which was until recently played by three teams.
