Suffolk County /ˈsʌfək/ is a suburban county on Long Island and the easternmost county in the U.S. state of New York. As of the 2010 census, the county's population was 1,493,350, estimated to have decreased to 1,492,583 in 2016, making it the fourth-most populous county in New York. Its county seat is Riverhead, though most county offices are located in Hauppauge. The county was named after the county of Suffolk in England, from where its earliest European settlers came.

Suffolk County incorporates the easternmost extreme of the New York City metropolitan area. The largest of Long Island's four counties and the second-largest of 62 counties in New York State, Suffolk measures 86 miles (138 km) in length and 26 miles (42 km) in width at its widest (including water).

Major scientific research facilities in Suffolk County include Brookhaven National Laboratory in Upton and Plum Island Animal Disease Center on Plum Island.

Suffolk County was part of the Connecticut Colony before becoming an original county of the Province of New York, one of twelve created in 1683. From 1664 until 1683 it had been the East Riding of Yorkshire. Its boundaries were essentially the same as at present, with only minor changes in the boundary with its western neighbor, which was originally Queens County but has been Nassau County since the separation of Nassau from Queens in 1899.
