2020–21 Penn State Nittany Lions basketball team

The 2020–21 Penn State Nittany Lions basketball team represented Pennsylvania State University in the 2020–21 NCAA Division I men's basketball season. They were led by interim head coach Jim Ferry and played their home games at the Bryce Jordan Center in University Park, Pennsylvania as members of the Big Ten Conference. They finished the season 11–14, 7–12 in Big Ten play to finish in a tie for 10th place. As the No. 10 seed in the Big Ten tournament, they defeated Nebraska before losing to Wisconsin in the second round.

On October 21, 2020, head coach Pat Chambers resigned after an internal investigation by the school into inappropriate conduct by Chambers. It had been reported in July that former player Rasir Bolton had left the program due to inappropriate comments to him by Chambers. New allegations surfaced after a later investigation by the school that led to Chambers resigning. Assistant coach Jim Ferry was named interim coach for the season.

Following the end of the season, the school hired Purdue assistant coach Micah Shrewsberry as head coach.
