The 2012 MasterCard Memorial Cup was a four-team, round-robin format ice hockey tournament played from May 18–27, 2012 at the Centre Bionest in Shawinigan, Quebec.

The tournament featured the London Knights, champions of the Ontario Hockey League (OHL); the Saint John Sea Dogs, champions of the Quebec Major Junior Hockey League (QMJHL); the Edmonton Oil Kings, champions of the Western Hockey League (WHL); and the Shawinigan Cataractes, who won the right to host the tournament over bids by the Saint John Sea Dogs, Halifax Mooseheads and Cape Breton Screaming Eagles.

The Cataractes win also gave the QMJHL back-to-back Memorial Cups for the first time since the Granby Prédateurs in 1996 and the Hull Olympiques in 1997.

Note: Shawinigan finished fourth based on head-to-head round-robin matchups but defeated Edmonton in the tiebreaker game.
