The 1988 Indiana Gubernatorial Election was held on November 8, 1988 in all 92 counties in the state of Indiana. Incumbent Governor Robert D. Orr, a Republican, was ineligible to run for a third consecutive term due to term limits set forth in the Indiana Constitution. In the general election, the Republican nominee, Lieutenant Governor John Mutz, was defeated by Democrat Indiana Secretary of State Evan Bayh by a margin of six percentage points. Bayh was the first Democrat to be elected Governor of Indiana since Roger D. Branigin's victory during the 1964 Democratic landslides twenty-four years previously.
