The 2003 MAAC Men's Ice Hockey Tournament was the 5th and final championship in the history of the conference.
Quarterfinal games were played at home team campus sites, while the final four games were played at the Hart Center in Worcester, Massachusetts, the home venue of the Army Black Knights.
After the 2003 season, both the Fairfield Stags and Iona Gaels discontinued their hockey programs.
The remaining 9 teams in the conference then formed Atlantic Hockey which began play in 2003-04.
