The 2015 Dallas municipal election was an election to determine the mayor in Dallas, Texas. The election day was May 9, 2015, and if a runoff election had been required, it would have been held on June 13, 2015. Incumbent Democratic Mayor Mike Rawlings ran and won re-election to a second term in office against challengers Marcos Ronquillo, an attorney, and write-in candidate Richard Sheridan, a retired engineer and anti-gay government activist.

Six of the current 14 members of the City Council ran unopposed, but eight other seats were contested. Historically less than 10% of voters participate in Dallas City Council elections, although 9 days of early voting were provided from April 27 through May 5. The Dallas County Elections office has published a map of these polling locations for reference.
