Local Area Information

Northwest Harbor is an unincorporated area and census-designated place (CDP) in Suffolk County’s Town of East Hampton on the south fork of Long Island, New York’s East End. It is bounded by the village of Sag Harbor on the west, Wainscott on the southwest, East Hampton North on the southeast and Springs on a small segment in the east. Along with the village of East Hampton, it shares the 11937 ZIP code with these neighborhoods except Sag Harbor and only partially with Wainscott.

The name Northwest Harbor also refers to Northwest Landing, East Hampton Town’s first port that became a primary whaling harbor before the Long Wharf in Sag Harbor was established in the late 1700s and replaced it. It also refers to the neighborhood in East Hampton Town called Northwest Woods as well as the bay on which the area is located and that provides access to Gardiners Bay and the Atlantic Ocean. The bay’s name is derived from its position relative to East Hampton Village and is adopted by the community.

In the 2020 US Census, Northwest Harbor had a land area of 14 square miles and was the sixth largest among the 194 CDPs on Long Island. Its population of a mere 4,637 was comparable to Montauk’s 4,318 in a 17-square-mile area, making them two of Long Island’s less populous CDPs.

Residential areas in Northwest Harbor consist of mainly single-family homes, a number of which are 3-bedroom homes and grander luxury residences with six or more bedrooms. There are also new constructions and homes with pools as well as first-floor bedrooms among other features and amenities. As a hamlet surrounded by water on three sides, it has a wealth of waterfront homes offering outstanding bay and harbor vistas.
