The 97th Grey Cup was played on November 29, 2009, at McMahon Stadium in Calgary, Alberta, and decided the Canadian Football League (CFL) champion for the 2009 season. The Montreal Alouettes came from behind to defeat the Saskatchewan Roughriders 28-27, on a 33-yard field goal by Damon Duval as time ran out. Duval had actually missed a first attempt, but Saskatchewan was penalized for having too many men on the field, allowing Duval a second field goal attempt.
Montreal running back Avon Cobourne was named the Most Valuable Player of the game. Alouettes slotback Ben Cahoon received the Dick Suderman Trophy as the Grey Cup's Most Valuable Canadian.
