Atlantic Hockey America (AHA) is a college ice hockey conference which operates primarily in the northeastern United States. It participates in NCAA Division I as an ice hockey-only conference. The conference was formed in 2023 by the merger of the men-only Atlantic Hockey Association and the women-only College Hockey America (CHA).
In 2010, the men's division of CHA collapsed and two of the remaining teams joined the Atlantic Hockey Association. At that time, the two leagues began working together by sharing a commissioner and administrative staff in order to streamline their operating costs. The arrangement worked well enough that by 2023, the two entities decided to formalize their relationship and announced that they were merging. The new league began with the 2024âÂÂ25 season and welcomed a new women's member, Delaware, in 2025. However, the number of men's members was reduced by one in the same year as AIC dropped its program to the Division II level, opting to place its hockey program in its all-sports conference of the NE-10. A little over a year later, Mercyhurst announced that it was discontinuing its men's program but would continue to support its women's team.
Two schools, RIT and Robert Morris, have programs in both the men's and women's divisions. Holy Cross, Lindenwood, Penn State and Sacred Heart each operate teams of both genders, but only one is a member of AHA. Mercyhurst, Niagara and Syracuse only have one varsity program active as of 2026 but each previously supported the other gender.
