Port Jefferson Historic Village & Port Jefferson Harbor

Port Jefferson (informally known as Port Jeff) is an incorporated village in the Town of Brookhaven in Suffolk County, New York on the North Shore of Long Island. Officially known as the Incorporated Village of Port Jefferson, the population was 7,983 as of the 2020 United States Census.

Port Jefferson was first settled in the 17th century and remained a rural community until its development as an active shipbuilding center in the mid-19th century. The village has since transitioned to a tourist-based economy. The port remains active as terminus of the Bridgeport & Port Jefferson Ferry, one of two commercial ferry lines between Long Island and Connecticut, and is supplemented by the terminus of the Long Island Railroad’s Port Jefferson Branch. It is also the center of the Greater Port Jefferson region of northwestern Brookhaven, serving as the cultural, commercial and transportation hub of the neighboring Port Jefferson Station, Belle Terre, Mount Sinai, Miller Place, and the Setaukets.

Port Jefferson is located at 40°56′46″N 73°03′44″W / 40.946103°N 73.062224°W / 40.946103; -73.062224, on the North Shore of Long Island.

Port Jefferson Harbor is a natural deep water harbor on the North Shore of Long Island. Setauket Harbor branches off to the west from the Harbor. One notable geographic feature is Pirate’s Cove, a small cove dredged in the early 20th century by the Seaboard Dredging Company. The original name was Seaboard Hole, but it was changed for the sake of appealing to tourists. Several large sand dunes (artificially created by the dredging) are found here.
