The John Henry Hammond House is a mansion at 9 East 91st Street on the Upper East Side in New York City. Since 1994, the Consulate-General of Russia in New York City has been located there. The purchase of land fronting on Fifth Avenue between 90th and 91st Streets by Andrew Carnegie, and the 1901 building of his mansion, saw Carnegie buy neighboring building lots in order to protect his investment. The entire north side of 91st Street between Fifth and Madison Avenues was purchased by Carnegie. Carnegie sold off lots to individuals who agreed to build substantial dwellings, and in 1903, a home was built at 9 East 91st Street by John H. Hammond, a New York City banker. The land, and possibly the house, was a wedding gift to Hammond and his wife from her father, William Douglas Sloane of the firm W. & J. Sloane.
