Long Island is located in the southeastern region of New York, just east of Manhattan. Stretching northeast into the Atlantic Ocean, Long Island contains four counties, two of which are boroughs (Queens and Brooklyn) of New York City, and two of which (Nassau and Suffolk) are mainly suburban or rural. In popular usage, the term "Long Island" generally refers only to Nassau and Suffolk counties in order to differentiate them from New York City, though all four counties on the island are part of the New York metropolitan area.
