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 centre for the city's May Day activities; the use of the building as a social centre; and the promotion of the performing arts - by hosting punk rock bands, and through its own drama collective.
