The 2012 Calder Cup playoffs of the American Hockey League began on April 19, 2012, with a slightly different playoff format than in other recent years. The sixteen teams that qualified, eight from each conference, will play a best-of-five series in the conference quarterfinals, and the playoffs will then continue with best-of-seven series for the conference semifinals, conference finals and Calder Cup finals.
The Norfolk Admirals defeated the Toronto Marlies in four games to win the Calder Cup for the first time in Norfolk's history.
