The Waterloo Warriors men's basketball team represents the University of Waterloo in the Ontario University Athletics (OUA) of U Sports men's basketball.

The Warriors have won the Wilson Cup, awarded to the OUA champions, 6 times: from 1974 to 1977, in 1983 and most recently in 1986.

The Warrior's basketball program was founded shortly after the university's inception in 1957 and has participated in every season since.

[1] The team, like all other sports teams at the university, have a rivalry with the nearby Wilfrid Laurier Golden Hawks, also located in Waterloo.

The matchup between the two teams in any varsity sport is often titled and advertised as "The Battle of Waterloo", in reference to the 17th century Battle of Waterloo.
