Long Island is an island located in southeastern New York, USA, just east of Manhattan. Stretching northeast into the Atlantic Ocean, Long Island contains four counties, two of which (Queens and Kings) are boroughs (Queens and Brooklyn) of New York City, and two of which (Nassau and Suffolk) are mainly suburban. Numerous bridges and tunnels through Queens and Brooklyn connect Long Island to the three other boroughs of New York City. Ferries connect Suffolk County northward across Long Island Sound to the state of Connecticut.
The longest island in the contiguous United States, Long Island extends 118 miles (190 km) from New York Harbor, and varies in width from 12 to 23 miles (19 to 37 km) between the northern (Long Island Sound) coast and the southern Atlantic coast. With an area of 1,401 square miles (3,629 km2), Long Island is the largest island in the contiguous U.S. and the 149th largest island in the world. The land area of Long Island is somewhat larger than that of the state of Rhode Island (1045 sq.mi.) and larger than any U.S. territory except Puerto Rico.
