The Wabash River Conference is an eight-member Indiana High School Athletic Association (IHSAA)-sanctioned conference located within Fountain, Parke, Vermillion, and Warren Counties in West Central Indiana. All of the participating schools are either 1A, 2A, or 3A (South Vermillion) institutions in rural counties. The conference began in 1964 with nine schools who had outgrown their county conferences or had them fold, and has had that number stay relatively consistent since. The only change since was the consolidation of two members, Turkey Run and Rockville, into Parke Heritage High School in 2018 reducing the number of members to 8.
