2018 New Hampshire gubernatorial election

The 2018 New Hampshire gubernatorial election took place on November 6, 2018, to elect the governor of New Hampshire. Incumbent Republican Governor Chris Sununu won re-election to a second term, defeating former state senator Molly Kelly. Sununu was the first incumbent Republican to win reelection as governor since Steve Merrill was reelected in 1994.

Primary elections were held on September 11, 2018. The gubernatorial election was coincident with races for the state legislature and the United States House of Representatives. This was one of eight Republican-held governorships up for election in a state won by Hillary Clinton in the 2016 presidential election.
