The 2010 New Orleans mayoral election was held on February 6, 2010, to elect the Mayor of New Orleans, Louisiana. Incumbent Democratic Mayor Ray Nagin was term-limited and ineligible to run for re-election to a third term.
Democrat Mitch Landrieu, the Lieutenant Governor of Louisiana, was elected mayor in a landslide and was sworn in on May 3, 2010.
Several candidates in multiple parties registered to run for the office of Mayor of New Orleans.
The 2010 New Orleans mayoral election occurred on the day before Super Bowl XLIV, the first (and only) Super Bowl for which the New Orleans Saints have ever competed. The year's highly successful football season brought about an unprecedented amount of local support for the team and resulted in relatively low voter turnouts due to preoccupation with citywide celebrations.
