About Northwest Harbor
Northwest Harbor is a hamlet and census-designated place (CDP) in the Town of East Hampton, Suffolk County, New York, United States. As of the 2020 census, Northwest Harbor had a population of 4,637.
It is named for the bay on the South Fork of Long Island connecting Sag Harbor, Shelter Island and the town of East Hampton to Gardiners Bay and the open waters of the Atlantic Ocean. The bay derives its name from being northwest of East Hampton village. The name "Northwest Harbor" is applied to the Northwest Woods neighborhood (sometimes shortened to simply "Northwest") of the town of East Hampton. It is also applied to Northwest Landing at Northwest Creek (a saltwater outlet from the inlet to the harbor) which was the first port for East Hampton and which became a major whaling port in the late 17th and early 18th centuries until it was replaced by Sag Harbor two miles to the west of the landing, where the water was deeper. Ships of Sag Harbor must pass through Northwest Harbor at the Cedar Point Lighthouse in order to reach Gardiners Bay and the open ocean.
