The 2008–09 George Mason Patriots men's basketball team began its 43rd season of collegiate play on November 15, 2008, versus the University of Vermont. The players were looking to continue the success from their 2007–2008 season where they won the 2008 Colonial Athletic Association tournament championship game and advanced to the 2008 NCAA men's basketball tournament. The 2008–09 Patriots had a 13–5 regular season record and were runners-up in the 2009 Colonial Athletic Association tournament. The team reached the 2009 National Invitation Tournament, but they lost in overtime to eventual tournament champion Penn State.
