About Riverhead
Riverhead (historically spelled River Head) is a hamlet and census-designated place (CDP) located within the Town of Riverhead in Suffolk County, on the North Fork of Long Island, in New York, United States. It is the town seat of the Town of Riverhead and the de jure county seat of Suffolk County. The population was 14,993 at the time of the 2020 census.
Situated at the mouth of the Peconic River, which empties into Peconic Bay where the North and South Forks of Long Island split, the hamlet is the official county seat of Suffolk County. In the 1960s, most of the county offices moved to the CDP of Hauppauge in the towns of Islip and Smithtown in the more populous western half of the county – a move which still spurs attempts for the town of Riverhead to lead the way for the secession of the five easternmost towns in the county to form Peconic County.
