The 2019 Hockey East Men's Ice Hockey Tournament was the 35th tournament in the history of the conference. It was played between March 15 and March 23, 2019, at campus locations and at the TD Garden in Boston, Massachusetts. Northeastern won their 3rd tournament and earned Hockey East's automatic bid into the 2019 NCAA Division I Men's Ice Hockey Tournament.
In a departure from the format of the last few years, just eight of the 11 teams will qualify for the 2019 Hockey East tournament. The top four teams in the league standings will host seeds five through eight on campus in the quarterfinals in the first round of the playoffs, while the remaining teams will be eliminated from championship contention.
The four quarterfinal winners will be reseeded again as they advance to the TD Garden in Boston for the semifinals and Championship Game.
