Suffolk County (/ˈsʌfək/ SUF-ək) is the easternmost county in the U.S. state of New York, constituting the eastern two-thirds of Long Island. Suffolk is bordered to its west by Nassau County, to its east by Gardiners Bay and the open Atlantic Ocean, to its north by Long Island Sound, and to its south by the Atlantic Ocean.
As of the 2020 United States census, Suffolk County's population was 1,525,920, its highest decennial count ever, making Suffolk the fourth-most populous county in the State of New York, and the most populous outside of the boroughs of New York City. Its county seat is Riverhead, though most county offices are in Hauppauge. The county was named after the county of Suffolk in England, the origin of its earliest European settlers.
