Slagsmålsklubben was a Swedish electronic music group from Norrköping, Östergötland. The group's name is a comically literal Swedish translation of the title of the novel and film Fight Club by Chuck Palahniuk. They have released five studio albums so far. Along with their side projects 50 Hertz and Häxor och porr, they were featured on Björk's 2005 remix album Army of Me: Remixes and Covers.
