Eastern Indiana Athletic Conference
The Eastern Indiana Athletic Conference is a distinguished, eight-member IHSAA-sanctioned high school athletic conference. Current members consist of Batesville, Connersville, East Central, Franklin County, Greensburg, Lawrenceburg, Rushville, and South Dearborn. All eight member schools are located in rural southeast Indiana, spread across Dearborn, Decatur, Fayette, Franklin, Ripley, and Rush counties. The EIAC was founded in 1956 when Brookville, Cambridge City, and Hagerstown of the East Central Conference joined with Aurora, Batesville, and Lawrenceburg of the Southeastern Indiana Conference. Batesville and Lawrenceburg are the only two of the original six founding schools that haven't consolidated or left the conference. North Dearborn joined the conference in 1962, which eventually consolidated into East Central in 1973. In 1974, Greensburg parted ways with the South Central Conference to join the EIAC. Aurora consolidated into South Dearborn in 1978 and Brookville consolidated into Franklin County in 1989. With the exception of 1962–66, 1973–74, 1977–85, and 1974–77, the conference had been a six-member league until 2013 when Connersville and Rushville joined.
This conference should not be confused with the Eastern Indiana Conference, a small-school conference in Northeast Indiana that existed from 1953 to 1975.
