The Sir Winston Churchill Bowl was one of two semi-final bowl games played in Canadian Interuniversity Sport football that would determine a participant in the Vanier Cup national championship. The trophy was originally donated and managed by McGill University to serve as an annual, often pre-season, invitational football contest between the sister universities of McGill and UBC in aid of the Canadian Paraplegic Association. The Churchill Bowl was retired in 2003 and replaced by the Mitchell Bowl.
