Bầu cử tổng thống Hoa Kỳ tại Ohio năm 2000

The 2000 United States presidential election in Ohio took place on November 7, 2000, and was part of the 2000 United States presidential election. Voters chose 21 representatives, or electors, to the Electoral College, who voted for president and vice president.

Ohio was won by Texas governor George W. Bush by a 3.51% margin of victory. Prior to the election, most news organizations considered Ohio a swing state. Bush performed strongly in most parts of rural Ohio. Gore kept the race close by running up big margins in Cuyahoga County, home of Cleveland. Gore also won the traditional working-class counties of Mahoning, Portage, and Trumbull counties. Gore only narrowly took Franklin County, home of Columbus, which at the time was a swing county but is now seen as reliably Democratic, having given Democratic nominees a majority of the vote in every election since. As of 2024, this was the last presidential election in Ohio where the Democrat won Clark County, home of Springfield.

Ohio kept its streak of voting for the winner in every election since 1964, but this was the first election since Ohio voted for Richard Nixon in 1960 where the state failed to back the national popular vote winner. Ohio was one of nine states that voted for Bill Clinton twice that Bush managed to flip. Had Gore won the state's electoral votes instead of Bush, the election would have gone his way. Bush became the first Republican to win the White House without carrying Erie County and Franklin County since Benjamin Harrison in 1888.
