Shillelagh Tournament

The Shillelagh Tournament was a Division I men's college ice hockey tournament hosted annually during the NCAA Division I men's ice hockey season by the Notre Dame Fighting Irish men's ice hockey program. It was first held during the 2008–09 NCAA Division I men's ice hockey season as the successor to the Lightning College Hockey Classic. After the Tampa Bay Lightning withdrew as tournament sponsor because of ownership changes, the Notre Dame Fighting Irish men's ice hockey program took control of the event, moving it to the Sears Centre in Hoffman Estates, Illinois.

Notre Dame won the inaugural Shillelagh Tournament, defeating the University of Minnesota Duluth 3–1 in the final game. After three seasons, the tournament was shelved for a couple years, leading some fans to believe it had run its course. But Notre Dame finally renewed it as a Thanksgiving tournament in November 2013 (rather than a New Year's tournament as it had been prior), in which the Irish were upset in the championship game. This renewal also moved the tournament from Hoffman Estates to Notre Dame's own Compton Family Ice Arena. The tournament did not return for the 2017-18 season.
