The Three Rivers Athletic Conference was a short-lived conference based in Southern Indiana, not to be confused with the Three Rivers Conference in northern Indiana, which still exists. The five schools that made the conference were very small, far-flung schools that were unable to find a home in closer leagues for various reasons. The league folded in 1989 due to travel concerns, with all the members becoming independent, and remaining so except for New Harmony, which closed in 2012.
