The name "Setauket" is derived from the historic Algonquian-speaking Setalcott Indians, who had lived in the area before its colonial period.
In 1655, a handful of land-speculating colonists orchestrated the purchase of the Setauket area from the local natives. The region's first European settlers were English migrants from New England.

During the 17th century, Setauket was synonymous with the colonial town of Brookhaven.
