Bầu cử tổng thống Hoa Kỳ tại Oregon năm 2000

The 2000 United States presidential election in Oregon was held on Tuesday, November 7, 2000, as part of the concurrent United States presidential election. Voters chose seven electors, or representatives to the Electoral College, to vote for the next president and vice president of the United States.

The state of Oregon voted for Democrat Al Gore over Republican George W. Bush by a narrow margin of 0.44%, or 6,765 votes. This made the state 0.07% to the right of the nation at-large and the closest to the national popular vote results. Oregon has been considered a blue state in recent years, voting for the Democratic Party in every presidential election since 1988. Despite this, Gore's performance was relatively weak considering the state's typical partisan lean. This is the closest that Oregon has come to voting for a Republican for president since Ronald Reagan carried the state in 1984.

This also marks the last election in which the margin of victory in Oregon was less than a percentage point, the last time that the Democratic candidate failed to win a majority in the state, and the last time that the state would vote more Republican than the nation. Four years later, John Kerry would win the state by a larger, yet somewhat modest, margin; from 2008 onward, Oregon would be considered a safely blue state on the presidential level. Almost eighty percent of registered voters came out to vote on election day, the highest in the country.

Bush became the first Republican ever to win the White House without carrying Washington County.
