2018–19 Phoenix mayoral special election

The 2018–19 Phoenix mayoral special election was held on November 6, 2018, to elect the new Mayor of Phoenix, Arizona. The election was officially nonpartisan; candidates ran on the same ballot. In the initial round of the election, since no candidate reached 50 percent plus one vote (as required by Phoenix City Charter), a runoff election was held on March 12, 2019, between the top two finishers.

In October 2017, then incumbent mayor Greg Stanton announced that he was running for the United States Congress in AZ's 9th congressional district, which includes much of Phoenix. Stanton resigned effective May 29, 2018, triggering a special election. The top two candidates from that election, Kate Gallego and Daniel Valenzuela, both fell short of the required 50 percent of the vote, therefore the mayoral race was decided by a final runoff election, which Gallego won.

Phoenix councilwoman Thelda Williams served as temporary mayor until Gallego took office.
