1998 NCAA Division III men's ice hockey tournament

It concluded with Middlebury defeating Wisconsin-Stevens Point in the championship game 2-1.

All Quarterfinals matchups were held at home team venues, while all succeeding games were played in Plattsburgh, New York.

The championship marked the fourth in a row for Middlebury, a record for all levels of men's ice hockey.

There were no automatic bids, however, conference tournament champions were given preferential consideration.

No formal seeding was used while quarterfinal matches were arranged so that the road teams would have the shortest possible travel distances.
