Island (pop., 2000: 7,448,618), southeastern New York, U.S., lying between Long Island Sound and the Atlantic Ocean. It has four counties: Kings, Queens, Nassau, and Suffolk. Kings County (the borough of Brooklyn) and Queens County (the borough of Queens) form part of New York City. At its western end it is separated from the Bronx and Manhattan by the East River and from Staten Island by the Narrows. It is 118 mi (190 km) long, 12–23 mi (19–37 km) wide, and has an area of 1,401 sq mi (3,629 sq km). Its eastern portion has many beaches; it serves as a recreation area for New York City. Its southern shore, lined by sand spits (seeFire Island), shelters several bays, including Jamaica Bay. Originally inhabited by Indians (mostly Delaware), it was included in a grant to the Plymouth Co. It was settled by Dutch and English, but the whole island became part of the British colony of New York in 1664. It was the site of the Battle of Long Island (Aug. 27, 1776), an American defeat in the American Revolution.
