The 1989 Colonial Athletic Association men's basketball tournament was held March 4–6 at the Hampton Coliseum in Hampton, Virginia.[1]
George Mason defeated in the championship game, 78–72, to win their first CAA men's basketball tournament. The Patriots, therefore, earned an automatic bid to the 1989 NCAA tournament, their first-ever NCAA tournament bid.
