Eastport town is built on Shinnecock land. The present hamlet dates to 1772, when two men built the dam that formed what has come to be called the West Pond, which created a dividing line between Brookaven and Southampton. They built two mills below the dam, a saw mill and a gristmill. By 1845, the area to the east of the West Pond had come to be known as Waterville. The land to the west was called Seatuck, after a nearby creek. When, in 1860, the United States Postal Department needed to define the town to deliver mail, it combined the two areas. The name Seatuck was dropped for being too similar to Setauket, New York and the combined area was named Eastport.
