The 2020–21 Belmont Bruins men's basketball team represented Belmont University in the 2020–21 NCAA Division I men's basketball season.

The Bruins, led by second-year head coach Casey Alexander, played their home games at the Curb Event Center in Nashville, Tennessee as members of the Ohio Valley Conference.

Because of a limited National Invitation Tournament due to COVID-19, the Bruins did not receive an automatic bid to the NIT for being regular season champions.

They defeated Eastern Kentucky and Murray State to win the championship of the OVC tournament.

As a result, they received the conference's automatic bid to the NCAA tournament.
