2000 United States presidential election in Massachusetts

The 2000 United States presidential election in Massachusetts took place on November 7, 2000, and was part of the 2000 United States presidential election. Voters chose 12 representatives, or electors to the Electoral College, who voted for president and vice president.

Massachusetts is one of the most reliable blue states in the nation: no Republican has won the state since Ronald Reagan in 1984. Massachusetts had been a Democratic-leaning state since 1928 and a Democratic stronghold since 1960, and has maintained sizable Democratic margins since 1996. Gore handily won Massachusetts by a 27% margin against George W. Bush; neither candidate actively campaigned in the state, although the wives of the Democratic candidates, Tipper Gore and Hadassah Lieberman, held a rally in Lieberman's hometown of Gardner. Gore won every county and congressional district.

Bush became the first Republican ever to win the White House without carrying Barnstable County. As of 2024, this is the last time that a Democratic presidential nominee has failed to reach 60 percent of the vote in Massachusetts. This is also the last time that the towns of Ashby, Charlton, Douglas, East Bridgewater, Middleborough, Middleton, Lakeville, and North Brookfield voted Democratic in a presidential election, and the last time that the towns of Chatham, Chesterfield, Orleans, Otis, and Rowe voted Republican, and the first time since 1944 where the city of Attleboro failed to vote for the winner of the presidential election.

With 6.42% of the popular vote, Massachusetts proved to be Ralph Nader's third-best state in the 2000 election after Alaska and neighboring Vermont. Nader received 36.2% of the vote in the town of Wendell.
