The 2020–21 Montana State Bobcats men's basketball team represented Montana State University in the 2020–21 NCAA Division I men's basketball season.

The Bobcats, led by second-year head coach Danny Sprinkle, played their home games at Brick Breeden Fieldhouse in Bozeman, Montana as members of the Big Sky Conference.

In a season limited due to the ongoing COVID-19 pandemic, they finished the season 13–10, 8–6 in Big Sky play to finish in a tie for fourth place.

They defeated Idaho State and Southern Utah before losing to Eastern Washington in the championship of the Big Sky tournament.

They received the #5 seed in the Big Sky tournament, and were slated to go up against the #4 seed Portland State in the quarterfinals, but the tournament was cancelled due to the ongoing COVID-19 pandemic.
