The 1990 Colonial Athletic Association men's basketball tournament was held March 3–5 at the Richmond Coliseum in Richmond, Virginia.[1] 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.
