The 2012 Vanier Cup, the 48th edition of the Canadian university football championship, took place on Friday, November 23, 2012 at Rogers Centre in Toronto. The game featured a rematch of the previous year's Vanier Cup game as the McMaster Marauders attempted to become repeat champions against the Laval Rouge et Or. This was the second time in Vanier Cup history that the same two teams played each other in consecutive years.

The Vanier Cup is a post season college football championship game, used to determine the national champion in U Sports football. The game is the final for the winners of the Uteck Bowl and the Mitchell Bowl. In turn, the participating teams are determined by the winners of 4 bowl games: the Loney Bowl (AUS), Hardy Cup, Dunsmore Cup (RSEQ), and Yates Cup (OUA).
