The 1990 Memorial Cup occurred May 5-May 13 at the Copps Coliseum in Hamilton, Ontario. Participating teams were the Ontario Hockey League champion Oshawa Generals and runner-up Kitchener Rangers, as well as the winners of the Quebec Major Junior Hockey League and Western Hockey League which were the Laval Titan and Kamloops Blazers. The original host team, the short-lived Dukes of Hamilton, were forced to drop out after only winning eleven games in the 1989–90 OHL season. Oshawa won their 4th Memorial Cup, defeating Kitchener in the final game.
