The University of Manitoba Students' Union (UMSU) is the university-wide representative body for undergraduate students at the University of Manitoba, located in Winnipeg, Manitoba. UMSU was established in 1919, replacing the former University of Manitoba Students' Association founded in 1914. Its head office is located in UMSU University Centre—a large, Modernist architecture building designed by Canadian architect Isadore (Issie) Coop at UM's Fort Garry Campus that serves as the university's activity hub.
