The 2018 Connecticut gubernatorial election took place on November 6, 2018, to elect the next governor and lieutenant governor of Connecticut, concurrently with the election of Connecticut's Class I U.S. Senate seat, as well as other elections to the United States Senate in other states, elections to the United States House of Representatives, and various state and local elections. This race's Democratic margin of victory was the closest to the national average of 3.1 points. (It was 0.1 point more Democratic.)
As Connecticut does not have gubernatorial term limits, incumbent Democratic governor Dannel Malloy was eligible to run for a third term, but declined to do so. After the resignation of Kansas governor Sam Brownback in January 2018, Malloy became the most unpopular governor in the United States. The general election was between 2006 Democratic U.S. Senate nominee Ned Lamont, and Republican financial executive Bob Stefanowski. Independent candidate and former Republican Oz Griebel has been called a spoiler candidate for Stefanowski, earning 3.89% of the vote.
