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 first time in Vanier Cup history that the same two teams played each other in consecutive years. The Vanier Cup was played on the same weekend it hosted the 100th Grey Cup and was part of the week-long festivities that were planned for the event. This marked the second consecutive year that the two games were played in the same city on the same weekend; after the 47th Vanier Cup and 99th Grey Cup were played in Vancouver.
The Rouge et Or defeated the McMaster Marauders 37-14, winning its seventh Vanier Cup. The 48th Vanier Cup also set an all-time record for attendance, with a crowd of 37,098.
