The 2018 Tallahassee mayoral election took place on August 28 and November 6, 2018, to elect the mayor of Tallahassee, Florida.
Incumbent mayor Andrew Gillum decided to focus his campaign on the 2018 Florida gubernatorial election instead of seeking re-election which opened up a new seat for the mayor's office. A blanket primary was held on August 28 with both John E. Dailey and Dustin R. Daniels receiving the most votes. Because neither candidate received a majority, a run-off election was held on November 8. From there, Dailey defeated Daniels by a close margin of 51% to 49%.
