1976 United States presidential election in Ohio

The 1976 United States presidential election in Ohio took place on November 2, 1976. All 50 states and the District of Columbia were part of the 1976 United States presidential election. State voters chose 25 electors to the Electoral College, who voted for president and vice president.

Ohio was won by former Georgia Governor Jimmy Carter (D) by a margin of 0.27%, which made the state almost 2% more Republican than the nation-at-large. As of the 2024 presidential election, this is the last election in which Adams County and Brown County voted for a Democratic presidential candidate, the last time until 2020 when Wood County voted for a losing candidate, and the last time that a Democrat would win Ohio while losing neighboring Michigan. It would also be the last election in which a Democratic Candidate won the state by under 1%, as Presidents Barack Obama and Bill Clinton won Ohio in both of their runs by more than 1%

The state was not only one of the closest states in the election, but it was called for Carter after he won Wisconsin, the tipping-point state of the election. Ohio, Mississippi, and Wisconsin were the only three states that Carter won without receiving above 50 percent of the vote. Unlike with Mississippi, Wisconsin and Ohio were the two closest states that Carter won, and if Carter had lost both, he would have lost the election to Ford.
