The 2021–22 Oklahoma State Cowboys basketball team represented Oklahoma State University during the 2021–22 NCAA Division I men's basketball season. The team was led by fifth-year head coach Mike Boynton, and played their home games at Gallagher-Iba Arena in Stillwater, Oklahoma as a member of the Big 12 Conference.
On November 3, 2021, the NCAA ruled Oklahoma State ineligible for postseason play for the season due to player receiving improper benefits.[1]
In a season limited due to the ongoing COVID-19 pandemic, the Cowboys finished the 2020–21 season 21–9, 11–7 in Big 12 play to finish in fifth place. They defeated West Virginia and Baylor in the Big 12 tournament before losing to Texas in the championship game. They received an at-large bid in the NCAA tournament as the No. 4 seed in the Midwest Region where they defeated Liberty in the first round before losing to Oregon State in the second round.
