The 1985 NCAA Division III Men's Ice Hockey Tournament was the culmination of the 1984–85 NCAA Division III men's ice hockey season, the 2nd such tournament in NCAA history. It concluded with RIT defeating Bemidji State 5-1. All Quarterfinals matchups were held at home team venues, while all succeeding games were played in Schenectady, New York.

Because neither of the two western conferences held a conference tournament the NCAA had all western schools play collectively in the Western Intercollegiate Hockey Association. At the conclusion of the regular season the top 8 teams, regardless of their conference, were invited to play in the WIHA tournament. Though the tournament was arranged by the NCAA it is not considered as part of the NCAA tournament and is displayed here for reference. As a result of both the MIAC and NCHA beginning conference playoffs the following year the WIHA was dissolved.

The tournament featured three rounds of play. In the Quarterfinals, teams played two-game aggregate series to determine which school advanced to the semifinals. Beginning with the semifinals all games became Single-game eliminations. The winning teams in the semifinals advanced to the National Championship Game with the losers playing in a Third Place game. The teams were seeded according to geographic proximity in the quarterfinals so the visiting team would have the shortest feasible distance to travel.
