Northwest Crossroads Conference

The Northwest Crossroads Conference is a seven-member IHSAA-sanctioned athletic conference. Six of the seven institutions are in Lake County, while the sixth, Kankakee Valley, is in neighboring Jasper County. This conference was created in 2007, following the disbandment of the Lake Athletic Conference. Griffith left the conference after the 2016–17 school year to join the Greater South Shore Athletic Conference (IHSAA).

Hanover Central, in southern Lake County, joined the conference as its seventh member starting in 2023. Illiana Christian High School will join the conference in the 2025-26 school year, leaving the Greater South Shore Conference.
