Hoosier Heartland Conference

The Hoosier Heartland Conference is an IHSAA-Sanctioned Athletic Conference in North Central Indiana. It comprises mainly single A and smaller AA schools. Lafayette Central Catholic joined the Hoosier Athletic Conference after the 2010–11 school year, and was replaced by Sheridan, who joined 2012. With the major conference realignment in Indiana in 2015, the conference picked up four schools from neighboring conferences that were folding, as well as a football-only member to balance the new football divisions. However, with the Midwest Conference reforming, the conference will be down to eight schools (seven in football) for the 2018–19 school year, as Delphi will rejoin the conference in 2019.

Membership

 * 1) Delphi played in the HAC from 1998 to December 17, 2015, when it was removed from the conference, and played as an Independent until rejoining the HHC. Since the departure happened in the middle of the school year instead of during the summer, the exit date is listed as 2016, since the school completed the fall season sports as conference members.
