List of counties in New York in the context of "NYC"

New York, often called New York City (NYC), is the most populous city in the United States. It is located at the southern tip of New York State on New York Harbor, one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with its respective county. It is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy.

With an estimated population in July 2024 of 8,478,072, distributed over 300.46 square miles (778.2 km), the city is the most densely populated major city in the United States. New York City has more than double the population of Los Angeles, the country's second-most populous city. Over 20.1 million people live in New York City's metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, both the largest in the U.S. New York City is one of the world's most populous megacities. The city and its metropolitan area are the premier gateway for legal immigration to the United States. An estimated 800 languages are spoken in New York City, making it the most linguistically diverse city in the world. The New York City metropolitan region is home to the largest foreign-born population of any metropolitan region in the world, approximately 5.9 million as of 2023.

Long Island is a densely populated continental island in southeastern New York state, extending into the Atlantic Ocean. It constitutes a significant share of the New York metropolitan area in both population and land area. The island extends from New York Harbor 118 miles (190 km) eastward into the ocean with a maximum north–south width of 23 miles (37 km). With a land area of 1,401 square miles (3,630 km), it is the largest island in the contiguous United States and the 11th largest island in the U.S.

Long Island is divided among four counties with Kings (Brooklyn), Queens, and Nassau counties occupying its western third and Suffolk County its eastern two-thirds. To what extent Brooklyn and Queens are considered with Long Island is a matter of debate. Geographically, both Kings and Queens county are located on the Island, but some argue they are culturally separate from Long Island. Long Island may refer both to the main island and the surrounding outer barrier islands. Long Island is separated from Manhattan Island and the Bronx by the East River tidal estuary in the west part of the island. North of the island is Long Island Sound, across which lie Westchester County, New York, and the state of Connecticut. Across the Block Island Sound to the northeast is the state of Rhode Island. Block Island, which is part of Rhode Island, and numerous smaller islands extend farther into the Atlantic Ocean. To the extreme southwest, Long Island, at Brooklyn, is separated from Staten Island and the state of New Jersey by Upper New York Bay, The Narrows, and Lower New York Bay.

The Supreme Court of the State of New York is the superior court in the Judiciary of New York. It is vested with unlimited civil and criminal jurisdiction, although in many counties outside New York City it acts primarily as a court of civil jurisdiction, with most criminal matters handled in county courts.

New York is the only state where supreme court is a trial court rather than a court of last resort (which in New York is the Court of Appeals). Also, although it is a trial court, the Supreme Court sits as a "single great tribunal of general state-wide jurisdiction, rather than an aggregation of separate courts sitting in the several counties or judicial districts of the state." The Supreme Court is established in each of New York's 62 counties.

Suffolk County (/ˈsʌfək/ SUF-ək) is the easternmost county in the U.S. state of New York, constituting the eastern two-thirds of Long Island. It is bordered to its west by Nassau County, to its east by Gardiners Bay and the open Atlantic Ocean, to its north by Long Island Sound, and to its south by the Atlantic Ocean.

As of the 2020 United States census, the county's population was 1,525,920, its highest decennial count ever, making Suffolk the fourth-most populous county in the State of New York, and the most populous outside of the boroughs of New York City. Its county seat is Riverhead, though most county offices are in Hauppauge. The county was named after the county of Suffolk in England, the origin of its earliest European settlers.

Westchester County is a county located in the southeastern portion of the U.S. state of New York, bordering the Long Island Sound and the Byram River to its east and the Hudson River on its west.
