Centerport is a hamlet (and census-designated place) in Suffolk County, New York on the notably affluent North Shore of Long Island. Formerly known as Little Cow Harbor about 1700, Centreport in 1836, and then the present Centerport after 1895. The name refers to its geographic position midway between the east and west boundaries of the township of Huntington.
As of the United States 2000 Census, the CDP population was 5,446. It is located in the Town of Huntington. Huntington and its surrounding hamlets mark the east end of Long Island's renowned "Gold Coast", the name deriving from the traditional wealth and gentility associated with the area. The association dates back to the early twentieth century in which many affluent families built their homes along the coast. In Centerport, an example of this is the mansion of William Kissam Vanderbilt II, otherwise known as the Vanderbilt Estate.
Whereas Centerport is highly residential, characterized by windy driveways and beachfront hills, the town of Huntington is famous for its bustling "village", an area in the center of town filled with quaint shops, art galleries, restaurants, pubs, and spas. Over the years, it has become something of an attraction, garnering visitors from all over Long Island.
