The 2018 WCHA Men's Ice Hockey Tournament was the 59th conference playoff in league history and 64th season where a WCHA champion was crowned. The 2018 tournament was played between March 2 and March 17, 2018, at four conference arenas, with the championship game being hosted by Northern Michigan at their home rink, Berry Events Center. By winning the tournament, Michigan Tech was awarded the Broadmoor Trophy and received the WCHA's automatic bid to the 2018 NCAA Division I Men's Ice Hockey Tournament.
The first two rounds of the postseason tournament featured a best-of-three games format. The top eight conference teams participated in the tournament. Teams were seeded No. 1 through No. 8 according to their final conference standings, with a tiebreaker system used to seed teams with an identical number of points accumulated. The higher seeded teams each earned home ice and host one of the lower seeded teams.
The final was a single game held at the campus site of the highest remaining seed.
