The Northwest Crossroads Conference is a six-member IHSAA-sanctioned athletic conference. Five of the six 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, plans to join the conference as its seventh member starting in 2023.
