History
Eastport dates to the 1730s when a gristmill was built there. It started as two hamlets, Seatuck and Waterville, and in the 1850s applied for a post office by the name of Seatuck. It was refused because it was too similar to Setauket, New York. It was renamed Eastport. In the first half of the 20th century it was the capital of the production of Long Island ducks, producing 6.5 million ducks from 29 farms a year going to market. At one time, the western portion of Eastport, located in the town of Brookhaven, was called "Seatuck", and the eastern portion, located in Southampton, was known as "Waterville". In the last twenty years, practically all duck farms were phased out and the descendants of the original farmers sold the valuable waterfront property for residential development projects.
