The 2008–09 Florida Gators men's basketball team represented the University of Florida in the sport of basketball during the 2008–09 college basketball season. The Gators competed in Division I of the National Collegiate Athletic Association (NCAA) and the Eastern Division of the Southeastern Conference (SEC). They were led by head coach Billy Donovan, and played their home games in the O'Connell Center on the university's Gainesville, Florida campus. The Gators were looking to build on their 24–12 record from the 2007–08 season.
Preseason
Entering the season, the Gators had to overcome the loss of Marreese Speights, who left for the 2008 NBA draft after his sophomore season with the Gators. (Speights was selected in the draft by the Philadelphia 76ers.) To replace him, the Gators added six freshmen to the team. The Gators won their two preseason games against Rollins and Warner.
