Where Is Long Island?

Long Island occupies the southeastern corner of New York State and is one of the most recognizable geographic regions in the United States. The island extends approximately 118 miles from west to east, beginning at New York Harbor and continuing to its easternmost points at Montauk on the South Fork and Orient Point on the North Fork.

To the north, Long Island is bordered by Long Island Sound, which separates it from Connecticut. To the south lies the Atlantic Ocean, home to many of the island’s most famous beaches, including Jones Beach State Park, Robert Moses State Park, and the barrier islands of Fire Island National Seashore.

Geographically, Long Island includes four counties: Kings (Brooklyn), Queens, Nassau County, and Suffolk County. While Brooklyn and Queens are officially part of New York City, the term “Long Island” is commonly used to describe Nassau and Suffolk counties, which encompass hundreds of villages, hamlets, parks, beaches, and waterfront communities.

Its convenient location places Long Island within easy reach of New York City while offering a distinctly different lifestyle characterized by scenic coastlines, charming downtowns, vineyards, nature preserves, and historic landmarks.
