Bầu cử thống đốc Massachusetts năm 2018

The 2018 Massachusetts gubernatorial election took place on November 6, 2018, to elect the governor and lieutenant governor of the Commonwealth of Massachusetts. Republican Governor Charlie Baker and Lieutenant Governor Karyn Polito won election to a second term in office, defeating Democratic challengers Jay Gonzalez and Quentin Palfrey, respectively. Candidates were selected in the primary election held on September 4, 2018.

This was one of eight Republican-held governorships up for election in a state that Hillary Clinton won in the 2016 presidential election. Despite Massachusetts's Democratic lean at the presidential level, Charlie Baker retained high approval ratings and was expected to safely win re-election. Shortly after polls closed at 8 p.m. local time, the Associated Press declared the race in favor of incumbents Baker and Polito. Shortly after 9 p.m. location time, Gonzalez conceded the election.

Baker was re-elected with the highest vote total in the history of Massachusetts gubernatorial elections and by the widest margin since Bill Weld was re-elected governor in 1994. He won many of the Commonwealth's most populated cities, including Worcester, New Bedford, and Springfield. Baker almost won Boston, losing it by only around 3,000 votes, an extraordinary showing for a statewide Republican candidate in a major city. Baker also carried every county in the state.

As of 2026, this is the last time Republicans won a statewide election in Massachusetts.
