The 1986 Indiana secretary of state election was held on November 4, 1986, to elect the secretary of state of Indiana. Republican incumbent Edwin Simcox did not seek a third term. Democratic attorney Evan Bayh defeated Republican attorney Robert O. Bowen by seven percentage points.
Bayh would not serve out a full term as Secretary of State of Indiana as he would go on to resign in 1989 to take office after winning the 1988 Indiana gubernatorial election.
