Riverhead is a census-designated place (CDP) roughly corresponding to the hamlet (unincorporated community) by the same name located in the town of Riverhead in Suffolk County, New York on Long Island. The CDP's population was 13,299 at the 2010 census.
Situated at the mouth of the Peconic River which empties into Peconic Bay and at the intersection where the North and South Forks of Long Island split, Riverhead is the official county seat of Suffolk County. In the 1960s most of the county offices moved to Hauppauge in the more populated western half of the county—a move which still spurs attempts for Riverhead to lead the way for the secession of eastern Long Island towns to form Peconic County.
