Bầu cử thống đốc California năm 2018

The 2018 California gubernatorial election was held on November 6, 2018, to elect the governor of California, concurrently with elections for the rest of California's executive branch, as well as elections to the United States Senate and elections to the United States House of Representatives and various state and local elections. Incumbent Democratic Governor Jerry Brown was ineligible to run for a third consecutive term due to term limits. The race was between the incumbent Democratic Lieutenant Governor Gavin Newsom and businessman John H. Cox, a Republican, who qualified for the general election after placing first and second in the June 5, 2018 primary election.

Newsom won in a landslide, with 62% of the vote, the biggest victory in a gubernatorial race in California since Earl Warren won re-election in 1950, and the biggest victory for a non-incumbent since 1930. The election also marked the first time in 40 years since Orange County had voted for the Democratic candidate since Jerry Brown won it in 1978, and the first time Democrats won three consecutive gubernatorial elections in the state's history. Newsom was sworn in on January 7, 2019.
