The New England Hockey Conference men's tournament began as the 'ECAC East Tournament' in 1985, a year after ECAC 2 downgraded to Division III and during the season where the conference formally split into two separate entities. For most of its existence the tournament was an 8-team format but on occasion the top seed would receive a bye into the semifinal round. For a few years during the late 1990s the tournament was expanded to include 10 teams but this was abandoned when nine teams left to form the ice hockey division of the NESCAC. Beginning with the 2004 tournament, the top seeded team to reach the semifinal round served as host for all semifinal and championship games regardless of their participation. This arrangement was abandoned after the 2013 tournament and the final two rounds were placed on different weekends. The 2021 tournament was cancelled due to the COVID-19 pandemic.
