Greenport is a village in Suffolk County, on the North Fork of Long Island, in New York, United States. The population was 2,197 at the 2010 census. The Incorporated Village of Greenport is located entirely within the Town of Southold and is the only incorporated community in the town. Greenport was a major port for its area, having developed a strong fishing and whaling industry in the past, although currently there are only a handful of commercial fishing vessels operating out of the village. More recently the tourism industry has grown substantially too, especially in the summer.
