Hausmania is a self-governed cultural house in Oslo, Norway. It is run by a group of underground artists based on collectivist ideology. It is located in Hausmannsgate 34 in Oslo and is a fertile ground for avant-garde art. Also, next door it contains the experimental music venue Kafe Hærverk
A group of artists began to use the centre in winter 2000 and it was rented from the state property owner Statsbygg in 2003. After some problems with the municipality in 2004, the centre is now established as a cultural centre and is making plans alongside the Vestbredden squat (Hausmannsgate 40) to be a “pilot project in inner city ecology, local governance, housing and culture”. 
The 5000 m2 centre provides space for artists' ateliers, practice rooms, exhibitions and other events. There are three galleries, a skate hall and an internet cafe.
There is a non-commercial vegan café called Blackeyedbean which serves mainly organic and fair trade products. 
The Grusomhetens Teater (Theatre of Cruelty) managed by Lars Øyno is located within its perimeters.
Located across the street from the main complex is Taxi Take Away, an independent bar/nightclub with occasional live music. While not run by Hausmania, you can meet many of its residents there, at both sides of the counter.
