1990 CAA men's basketball tournament

The 1990 Colonial Athletic Association men's basketball tournament was held March 3–5 at the Richmond Coliseum in Richmond, Virginia. The Richmond Coliseum would remain the home of the tournament until 2014.

Richmond defeated top-seeded in the championship game, 77–72, to win their third CAA men's basketball tournament. The Spiders, therefore, earned an automatic bid to the 1990 NCAA tournament.
