The Hoosier Hills Conference is an eight-member, IHSAA-sanctioned athletic conference comprising large 4A,5A & 6A football-sized schools in Bartholomew, Clark, Floyd, Jackson, Jennings, Lawrence and Monroe in South Central and Southeast Indiana. Madison departed the conference in 2021, thereby reducing its size to seven member schools. Bloomington South joined in April 2026 thus bringing the membership back up to eight schools.
