2020 Summit League men's basketball tournament

The 2020 Summit League men's basketball tournament was the postseason men's basketball tournament for the Summit League for the 2019–20 season. All tournament games were played at the Denny Sanford Premier Center in Sioux Falls, South Dakota, from March 7–10, 2020. First-seeded North Dakota State defeated North Dakota, 89–53, to set the Summit League Tournament record for the largest margin victory in the title game.
