William Jay Gaynor (February 2, 1849 – September 10, 1913) was an American politician from New York City, associated with the Tammany Hall political machine. He served as the 94th mayor of the City of New York from 1910 to 1913, and previously as a New York Supreme Court Justice from 1893 to 1909. As mayor he was noted as a reformer who broke ranks and refused to take orders from the Tammany boss Charles Francis Murphy.
