2022 Massachusetts gubernatorial election

The 2022 Massachusetts gubernatorial election was held on November 8, 2022, to elect the governor of Massachusetts. Republican former state representative Geoff Diehl, Democratic state Attorney General Maura Healey, and Libertarian Kevin Reed sought to succeed incumbent Governor Charlie Baker, who did not seek re-election after two terms. This was one of six Republican-held governorships up for election in 2022 in a state carried by Joe Biden in the 2020 presidential election, and the only race in which the incumbent was retiring despite being eligible for re-election.

Primary elections were held on September 6, with Diehl and Healey winning against minimal opposition. Due to Massachusetts's strong liberal lean and Diehl's conservative political views, Healey was widely expected to win the election. The election was called for the Democrat shortly after polls closed, with Healey becoming the first woman ever elected governor of Massachusetts and the first openly lesbian governor to take office.

In addition, with the election of Kim Driscoll as lieutenant governor, Massachusetts became one of the first two states to simultaneously elect women as governor and lieutenant governor, along with Arkansas. Arkansas, however, elects the governor in a separate election from the lieutenant governor. Taking 63.7% of the vote, Healey's performance was the strongest of any Democratic gubernatorial candidate in the state since Michael Dukakis in 1986, the best performance in Massachusetts history for a non-incumbent Democrat, and the best performance for any non-incumbent since Channing Cox in 1920. Healey received over 1.5 million votes, the most ever received by a Democratic gubernatorial candidate in Massachusetts.

This election constituted the largest shift by partisan margin of any 2022 gubernatorial election, swinging from a 33.5 point margin of victory for the Republican in 2018 to a 29.1 point margin for the Democrat in 2022. Additionally, every county in the state flipped from Republican to Democratic; this was the first gubernatorial election in which every county flipped since the 2010 Wyoming election.
