Bầu cử thống đốc Washington năm 2012

The 2012 Washington gubernatorial election took place on November 6, 2012. Candidates in the election were chosen in an August 7, 2012 primary election, under the state's nonpartisan blanket primary system, which allows voters to vote for any candidate running in the race, regardless of party affiliation. The two candidates who received the most votes in the primary election qualified for the general election.

Incumbent Governor Christine Gregoire decided to retire rather than seek a third term. She endorsed fellow Democrat Jay Inslee, a U.S. Congressman, as her successor. On March 20, 2012, Inslee resigned from Congress in order to focus on his gubernatorial campaign.

Inslee and Republican Rob McKenna, the Attorney General of Washington, advanced to the general election. Inslee narrowly won the election, and McKenna conceded three days later.
