The Eastern Indiana Conference existed in Northeastern Indiana from 1953 to 1975. It consisted of schools from Adams, Blackford, Delaware, Jay, and Wells Counties. The conference is notable for having two county conferences (Adams and Jay) fold into it, in 1957 and 1967, respectively. However, two years after the Jay County Conference folded into the EIC, the four Jay County schools were the only programs left in the conference. This conference should not be confused with the Eastern Indiana Athletic Conference, which still exists and is based in southeastern Indiana.
