# 2025 NCAA Division III men's ice hockey tournament

The 2025 NCAA Division III men's ice hockey tournament is the culmination of the 2024–25 season, the 40th such tournament in NCAA history.

## Qualifying teams
### Change

Following the 2023–24 athletic season, the Division III Management Council decided to change the tournament selection process for multiple sports. First, the ratio of bids to teams was lowered from 1:6.5 to 1:6, which would give the men's bracket an additional bid. Additionally, the council merged pools B and C for selection of at-large bids. Since there were no active conferences that had less than the requisite six members for an automatic bid (Pool B) that change did not affect men's college hockey. Finally, the selection committee would be using the NCAA Power Index instead of PairWise Rankings for choosing the at-large bids.

### Teams

The tournament featured 14 teams selected in the following manner: (Pool A) ten teams received bids as a result of being conference tournament champions from conferences that possessed an automatic bid, (Pool B) four additional teams received at-large bids based upon their NCAA Percentage Index.

## Format

The tournament featured four rounds of play. All rounds were single-game elimination. Because there were five western bids, those teams could not be localized in a single quarterfinal bracket. This meant that some matches would have to be arranged based upon proximity rather than ranking.
First, the top two overall seeds (Curry and Hobart) received byes into the quarterfinal round while the remaining teams were seeded in the first round. The top 4 overall seeds were placed in separate brackets and arranged so that, were they to advance, the #1 seed would play the #4 seed. Before any other seeding was done, the easter-most qualifier from the west (Trine) was placed into the same first round match as the western-most lower-seeded team from the east (Oswego State). While both Hobart and Geneseo State were further west, those two teams were to serve as hosts for playoff games while Oswego would be playing on the road. In order to cut down on travel, the winner of that east-west match would automatically advance to play Hobart, a relatively short distance from Trine's campus.
The remaining teams were seeded according to their regions with the top-ranked remaining western team facing the lowest-ranked remaining western team. However, instead of placing the four remaining wester teams in the same bracket (which had been standard policy in tournaments past), they were split into two brackets so that the first round matches containing the second western seed and second eastern seeds in the first round would play the first seeds of the opposite region in the quarterfinal round. This was done in part to not disadvantage the two teams in the east-west first round match by requiring the winner to travel far more than any other team but also because the second western seed (St. Norbert) was the 5th-overall seed while the second eastern seed in the first round (Geneseo State) was the 6th-overall seed and placing them in the same brackets as the 4th- and 3rd-overall seeds respectively made for a more fair arrangement.
The higher-seeded team played host in all first round and quarterfinal matches.
