The 2010 Orange County, Florida, mayoral election took place on November 2, 2010. Incumbent Republican mayor Richard Crotty was unable to seek re-election due to term limits, and four candidates ran to replace him. A nonpartisan primary election was held on August 24, 2010, but because no candidate won a majority of the vote, former county commissioner Teresa Jacobs, a Republican, advanced to a runoff election against fellow county commissioner Bill Segal, a Democrat. Following a contentious general election, Jacobs was elected mayor over Segal in a landslide, winning her first term 68–32.
