The 2023–24 California Golden Bears men's basketball team represented the University of California, Berkeley, in the 2023–24 NCAA Division I men's basketball season.

The Golden Bears played their home games at Haas Pavilion as last season members of the Pac-12 Conference after 45 years before they will join the Atlantic Coast Conference in the 2024–25 season.

The Golden Bears started the year losing their first 12 games, the worst for any Power Five team.

They won three of their next four games, including two in conference play against Colorado and Stanford.

At the end of the year, Mark Fox was fired on March 9, 2023,[1] one day after losing their first-round game of the conference tournament.
