The 2023–24 Texas Tech Red Raiders basketball team represented Texas Tech University in the 2023–24 NCAA Division I men's basketball season as a member of the Big 12 Conference. The Red Raiders were led by first-year coach Grant McCasland. They played their home games at the United Supermarkets Arena in Lubbock, Texas.
The Red Raiders finished the 2022–23 season 16–16, 5–13 in Big 12 play to finish in a tie for last place. As the No. 9 seed the Big 12 tournament, they lost to West Virginia in the first round.
The day after the Red Raiders' final regular season game, Mark Adams was suspended for what the school called an "inappropriate, unacceptable, and racially insensitive comment" that he had made the previous week.[1] On March 8, 2023, Adams resigned.[2] On March 31, the school named North Texas head coach Grant McCasland the team's new head coach.[3]
