The 2023–24 Hawaii Rainbow Warriors men's basketball team represented the University of Hawaiʻi at Mānoa during the 2023–24 NCAA Division I men's basketball season. The Rainbow Warriors, led by Eran Ganot in his ninth season, played their games at SimpliFi Arena at Stan Sheriff Center as a member of the Big West Conference.
The team claimed the Acrisure Invitational in November, the first mainland tournament title in program history, and advanced to the semifinals of the Big West tournament for the second time in three seasons after defeating CSUN in the quarterfinals, where they fell to UC Davis.
Despite a second consecutive 20-win season, the team decided to not pursue a bid to the postseason.[1]
The Rainbow Warriors finished the 2022–23 season 22–11, 13–7 in Big West play, to finish in fourth place.[2] In the Big West tournament, they were defeated by Cal State Fullerton in the quarterfinals.[3]
