2011 Jacksonville mayoral election

The Jacksonville mayoral election of 2011 determined the Mayor of Jacksonville, Florida. A blanket primary with six candidates together on the same ballot took place March 22, 2011. As no candidate received a majority of the vote, a runoff election between the top two vote-getters, Republican Mike Hogan and Democrat Alvin Brown, took place on May 17, 2011. In a close race, Brown defeated Hogan to become Jacksonville's first African-American mayor.

The runoff saw Brown win the narrowest election in Jacksonville mayoral history. Brown had widely been considered an underdog.
