The 2018 New Mexico gubernatorial election took place on November 6, 2018, to elect the next governor of New Mexico, concurrently with the election of New Mexico'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 local elections. This was one of eight Republican-held governorships up for election in a state carried by Hillary Clinton in the 2016 presidential election.

Incumbent Republican governor Susana Martinez was term-limited and could not seek a third consecutive term. Following party primaries on June 5, 2018, U.S. Representative Steve Pearce was the Republican nominee and U.S. Representative Michelle Lujan Grisham was the Democratic nominee. Lujan Grisham won the election by a substantial margin, which in fact was a complete and exact reversal of the 2014 gubernatorial results. Her win also signaled a continuation of the pattern of the partisanship of the office changing every two terms, beginning with Gary Johnson's first election in 1994. Furthermore, the pattern of the partisanship changing with each officeholder was continued, a pattern first started after Toney Anaya left office in 1987. Furthermore, the margin between the candidates (57.2% to 42.8%) was the same as the previous election, albeit with the parties switched.
