The 1 in 12 Club refers to both a members' club and the building in which it is based, in Bradford, West Yorkshire, England. Owned and run by its membership as a collective based upon anarchist principles, its activities include social and political campaigning—most visibly as a hub for the city's May Day activities—and use of the building as a self-managed social centre and host for performing arts. In the 1980s it was one of the main locations for the UK crust and anarcho-punk scene, and in the 1990s played host to much of the country's straight edge metalcore scene.
