The 2012 WCHA Men's Ice Hockey Tournament was the 53rd conference playoff in league history and 58th season where a WCHA champion was crowned. The 2012 tournament was played between March 9 and March 17, 2012, at five conference arenas and the Xcel Energy Center in St. Paul, Minnesota. By winning the tournament, North Dakota received the Broadmoor Trophy and was awarded the Western Collegiate Hockey Association's automatic bid to the 2012 NCAA Division I Men's Ice Hockey Tournament.
The first round of the postseason tournament features a best-of-three games format. All twelve conference teams participate in the tournament. Teams are seeded No. 1 through No. 12 according to their final conference standing, with a tiebreaker system used to seed teams with an identical number of points accumulated. The top six seeded teams each earn home ice and host one of the lower seeded teams.
The winners of the first round series advance to the Xcel Energy Center for the WCHA Final Five, the collective name for the quarterfinal, semifinal, and championship rounds. The Final Five uses a single-elimination format. Teams are re-seeded No. 1 through No. 6 according to the final regular season conference standings, with the top two teams automatically advancing to the semifinals. All Final Five games will be broadcast by Fox Sports North and carried by Root Sports Rocky Mountain and Fox College Sports Central.
