York Avenue and Sutton Place are the names of a relatively short north-south thoroughfare in the Yorkville, Lenox Hill, and Sutton Place neighborhoods of the East Side of Manhattan, in New York City. The street is considered among the city's most affluent, and both portions are known for upscale apartments, much like the rest of the Upper East Side. The greater Sutton Place neighborhood, which sits north of the neighborhood of Turtle Bay, runs from 53rd Street to 59th Street and is bounded on the east by the East River and on the west by either First Avenue or Second Avenue. Sutton Square is the cul-de-sac at the end of East 58th Street, just east of Sutton Place; Riverview Terrace is a row of townhouses on a short private driveway that runs north from Sutton Square.

One Sutton Place North, a townhouse at the northeast corner of Sutton Place (dead end) and East 57th Street, was built as a residence for Anne Harriman Vanderbilt, widow of William K. Vanderbilt. Next door, the official residence of the Secretary-General of the United Nations is a four-story brick townhouse that was built in 1921 for Anne Morgan, daughter of financier J.P. Morgan, and donated as a gift to the United Nations in 1972. The Secretary's home is 0.6 miles (0.97 km) from the UN Headquarters. These townhouses have a park at the rear with FDR Drive running below (Sutton Place Tunnel) along the East River.
