An election for Mayor of New York City was held in November 1913.
Incumbent mayor William Jay Gaynor died on September 10. In the race to succeed him, Republican John Purroy Mitchel, running on an independent fusion ticket, defeated Democratic judge Edward E. McCall and Socialist newspaper editor Charles Edward Russell in a landslide.
As the 1913 mayoral election approached, the Citizens Municipal Committee of 107 set out to find a candidate that would give New York "a non-partisan, efficient and progressive government". They were assisted in this endeavor by the Fusion Executive Committee, led by Joseph M. Price of the City Club of New York. After nine ballots, John Purroy Mitchel was nominated as a candidate for mayor. During his campaign, Mitchel focused on modernizing and fighting corruption in the city government.
