The 1937 New York City mayoral election took place on November 2, 1937, in New York City. Incumbent Mayor Fiorello La Guardia, the Republican candidate, was reelected with 60.09% of the vote, defeating the Democratic candidate Jeremiah T. Mahoney, a lawyer and former New York Supreme Court justice, as well as other, third-party candidates. La Guardia was also the nominee of the American Labor Party, and additionally ran on the City Fusion and Independent Progressive ballot lines, while Mahoney ran on the Trade Union and Anti-Communist party lines.

Primaries were held on Thursday, September 16. U.S. Senator Royal S. Copeland ran in both the Republican and Democratic primaries as a critic of the New Deal with the support of Tammany Hall, but lost both to New Deal supporters La Guardia and Mahoney, respectively.

This is to date the last time a Republican mayoral candidate carried all five city boroughs.
