Carnegie Hill is a neighborhood within the Upper East Side, in the borough of Manhattan in New York City. Its boundaries extend from 86th Street on the south to 96th Street to the north, between Fifth Avenue (Central Park) on the west and Lexington Avenue on the east. The neighborhood is part of Manhattan Community Board 8. In the 2000s, the perceived northern boundary on Park Avenue has edged over East 96th street into what was traditionally Spanish Harlem, leading to that area sometimes being called Upper Carnegie Hill, especially by real-estate brokers. According to the official Carnegie Hill Neighbors website, Carnegie Hill extends from 86th to 105th Streets (between Fifth Avenue & Madison Avenue), but not including, Third Avenue.
The neighborhood is named for the mansion that Andrew Carnegie built at Fifth Avenue and 91st Street in 1901. Today the mansion houses the Cooper-Hewitt, National Design Museum, a branch of the Smithsonian Institution. Facing it on 91st Street is the Otto H. Kahn House, a Florentine palazzo, now housing the Convent of the Sacred Heart. A number of other townhouses in the area have been converted to schools, including the recent purchase of the William Goadby and Florence Baker Loew House on 93rd Street by the Spence School. The Lycée Français, housed in the former Virginia Graham Fair Vanderbilt House, held an additional townhouse space on 93rd between Fifth and Madison Avenue until 2005, when the property was sold to a private owner.
