2020–21 North Texas Mean Green men's basketball team

The 2020–21 North Texas Mean Green men's basketball team represented the University of North Texas during the 2020–21 NCAA Division I men's basketball season. The team was led by fifth-year head coach Grant McCasland, and played their home games at UNT Coliseum in Denton, Texas as a member of the West division of Conference USA. In a season limited due to the ongoing COVID-19 pandemic, they finished the season 18–10, 9–5 to finish in third place in the division. They defeated Middle Tennessee, Old Dominion, Louisiana Tech, and Western Kentucky to win the C-USA tournament championship. As a result, they received the conference's automatic bid to the NCAA tournament as the No. 13 seed in the South region. There they upset No. 4-seeded Purdue in the first round for the school’s first ever NCAA tournament victory, before losing to No. 5-seeded Villanova in the second round.
