About Setauket
Setauket is a hamlet and census-designated place (CDP) in the Town of Brookhaven, Suffolk County, New York, United States, on the North Shore of Long Island. As of the 2020 census, Setauket had a population of 3,986.
Setauket was founded in 1655, the first settlement in what would become the town of Brookhaven. Before the 2020 census, the community was part of the Setauket-East Setauket CDP. The area was split in 2020 into two separate CDPs: Setauket and East Setauket despite many in the community still considering it one locality.
Setauket was founded as an agricultural community in the mid-17th century, and was a regional center of activity during the American Revolutionary War, noted for the Culper spy ring and the Battle of Setauket. Many of Setauket's early structures are intact and now form the Old Setauket Historic District. The Setaukets remain a mostly residential area, while bordering the more commercial enclaves of Port Jefferson and Stony Brook. The handful of businesses within the community largely cater to the over 25,000 students of Stony Brook University, which is adjacent to the CDP.
