The Samuel J. Tilden House is a historic townhouse pair at 14-15 Gramercy Park South in Manhattan, New York City. Built in 1845, it was the home of Samuel J. Tilden (1814–1886), former governor of New York, a fierce opponent of the Tweed Ring and Tammany Hall, and the losing presidential candidate in the disputed 1876 election. Tilden lived in the brownstone from 1860 until his death in 1886. From 1881 to 1884, Calvert Vaux combined it with the row house next door, also built in 1845, to make the building that now stands, which has been described as "the height of Victorian Gothic in residential architecture" with Italian Renaissance style elements. Since 1906 it has been the headquarters of the National Arts Club, a private arts club.
