Suffolk County, New York is the easternmost county in the state of New York and constitutes the central and eastern two-thirds of Long Island. It is bordered by Nassau County to the west, the Atlantic Ocean to the south, Long Island Sound to the north, and Block Island Sound to the east. The county seat is the town of Riverhead, though major population centers include the towns of Brookhaven, Islip, and Huntington. Renowned for its coastal communities, agricultural heritage, and significant role in the American Revolution and Cold War aerospace development, it is a region of diverse landscapes and historical importance.

History

The area was originally inhabited by Native American tribes, including the Algonquian-speaking Montaukett and Shinnecock. European settlement began in the 17th century as part of the Colony of New York, with early English settlers from the New England Colonies establishing towns under the jurisdiction of the Province of New York. During the American Revolutionary War, the region was a center of British occupation and saw notable events like the Battle of Long Island and the Culper Spy Ring operating out of Setauket. In the 19th and 20th centuries, the county transformed from an agricultural and maritime economy, with industries like duck farming and oyster harvesting, into a major suburban region following the post-World War II expansion of the Long Island Rail Road and the Long Island Expressway. Key historical sites include the Sagamore Hill National Historic Site, home of President Theodore Roosevelt, and the Brookhaven National Laboratory, a pivotal site for nuclear research established after World War II.

According to the United States Census Bureau, the county has a total area of 2,373 square miles, of which 912 square miles is land and 1,461 square miles is water, giving it the largest area of any county in New York.
