The Pacific 8 Intercollegiate Hockey Conference (PAC-8) is a collegiate men's ice hockey conference that competes in Division 2 of the American Collegiate Hockey Association. The PAC-8 was originally only open to schools that belonged to the Pac-12 Conference; however, for the 2018-19 season, the league expanded to include other schools from outside that conference. These schools included Boise State, Eastern Washington, San Diego State, San Jose State, and Western Washington. Because the conference spans the entire west coast, a north and south division format was adopted.
