Atlantic Hockey America (AHA) began this season after a merger of the women's only hockey conference College Hockey America (CHA) and the men's only hockey conference Atlantic Hockey. Its predecessor, the CHA, formed in 2002 with four teams. Mercyhurst is the only original member remaining.

University of Delaware has announced the formation of a team to join the AHA for the 2025-26 season.
