The Great Lakes Valley Conference (GLVC) men's basketball tournament is the annual men's basketball championship tournament for the Great Lakes Valley Conference. The tournament was established in 1998, twenty years after the conference was founded in 1978. It is a single-elimination tournament and seeding is based on regular season records.^[1]

The tournament bracket has included as few as seven teams and as many as fifteen. The most common format has featured eight teams competing at the same predesignated neutral site as the GLVC women's basketball tournament. In 1998, 2008, 2009, and 2021, the quarterfinals were played on campus sites and the final four was held on the home court of the highest seed surviving the quarterfinals.

The tournament winner is conference champion and receives the GLVC's automatic bid to the NCAA Division II men's basketball tournament.
