The 1985 Hockey East Men's Ice Hockey Tournament was the 1st Tournament in the history of the conference. It was played between March 8 and March 16, 1985. Quarterfinal games were played at home team campus sites, while the final four games were, for the first time, played at the Providence Civic Center in Providence, Rhode Island. By winning the tournament, Providence received the Hockey East's automatic bid to the 1985 NCAA Division I Men's Ice Hockey Tournament.

The tournament featured three rounds of play. In the quarterfinals, the second seed and seventh seed, the third seed and sixth seeds, and the fourth seed and fifth seeds played a two-game series where an additional mini-game was played if the teams remained tied to determine the winner and advanced to the semifinals. In the semifinals, the first seed was matched against the lowest remaining quarterfinalist while the other remaining quarterfinalists met in a single-elimination game with the winners advancing to the championship game and the losers meeting in a third-place game. The tournament champion receives an automatic bid to the 1985 NCAA Division I Men's Ice Hockey Tournament.
