The 1985 AMCU-8 men's basketball tournament was held March 6–10, 1985 at the Hammons Student Center at Southwest Missouri State University in Springfield, Missouri.[2]
Eastern Illinois defeated hosts Southwest Missouri State in the title game, 75–64, to win their first AMCU/Summit League championship. However, the Panthers did not earn a bid to the 1985 NCAA Division I men's basketball tournament.
All eight conference members qualified for the tournament. First round seedings were based on regular season record, and the highest-seeded team in each game served as the host.
