Port Jefferson, New York

Port Jefferson (“Port Jeff”) is an incorporated village in the Town of Brookhaven on Long Island’s North Shore, about 50–60 miles east of Manhattan. With a scenic deep-water harbor, it serves as the cultural, commercial, and transit hub of the surrounding region.
History & Maritime Heritage
- First settled in the 17th century, it was originally known as Sowaysset or Drowned Meadow due to tidal marshes.
- In 1836, Captain William L. Jones built a causeway across the salt marsh, laying the foundation for today’s downtown Main Street. The village was renamed in honor of President Jefferson.
- By the mid-1800s, Port Jefferson became a major shipbuilding center, with firms constructing whaling vessels and freighters; remnants of this era include the preserved Mather House Museum and the historic Bayles Shipyard, both part of its heritage.
- Tourism replaced shipbuilding in the 20th century, though the Bridgeport & Port Jefferson Ferry, in operation since 1883, continues to link the village with Connecticut.
