The Mason-Dixon Collegiate Hockey Association (MDCHA) is a ACHA Division III club ice hockey league that comprises smaller colleges and universities in the Mid-Atlantic region USA. Division III club hockey offers smaller colleges and universities the opportunity to field competitive hockey teams without the financial burden of higher divisions or NCAA levels.
Loyola University Maryland, 2006-07 season's champion, left the conference for the 2007-08 season, while Alvernia University and Bucknell University joined the league.
Catholic University, 2008-09 season's champion, leaves the conference to join Blue Ridge Hockey Conference, while runner-up Alvernia University also moves from MDCHA to the Delaware Valley Collegiate Hockey Conference.
University of Maryland, College Park club ice hockey joined MDCHA for the 2009-2010 season. This is the second team the University of Maryland has formed. They have a D1 ACHA team, but have enough interest to create a second team that we would like to participate at the D3 ACHA level in the MDCHA.
