Monstrous Regiment Theatre Company is a British feminist theatre company established in 1975. Monstrous Regiment went on to produce and perform 30 major shows, in which the main focus was on women's lives and experiences. Performer-led and collectively organised, its work figures prominently in studies of feminist theatre in Britain during the 1970s and 1980s. No productions have been mounted since 1993, when financial support from the Arts Council of Great Britain was discontinued.
