New York is a state in the Mid-Atlantic and Northeastern regions of the United States, and is the country's third most populous state. The state is bordered by New Jersey, and Pennsylvania to the south, Connecticut, Massachusetts and Vermont to the east. The state has a water border with Rhode Island off the east coast of Long Island, as well as an international border with the Canadian provinces of Quebec and Ontario to the northwest. New York is often referred to as New York State to distinguish it from New York City.

New York City, which is the largest city in the United States, is known for its history as a gateway for immigration to the United States and its status as a financial, cultural, transportation, and manufacturing center. It was named after the 17th century Duke of York, James Stuart, future James II and VII of England and Scotland.

New York was inhabited by the Algonquin, Iroquois, and Lenape Native American groups at the time Dutch and French nationals moved into the region in the early 17th century. First claimed by Henry Hudson in 1609, the region came to have Dutch forts in Fort Orange, near the site of the present-day capital of Albany in 1614 and was colonized by the Dutch in 1624, at both Albany and Manhattan; it later fell to British annexation in 1664. About one third of all of the battles of the Revolutionary War took place in New York. New York became an independent state on July 9, 1776 and enacted its constitution in 1777. The state ratified the United States Constitution on July 26, 1788 to become the 11th state. According to the US Department of Commerce, it is also the state of choice for foreign visitors, leading both Florida and California in tourism.

New York covers 54,556 square miles (141,299 km²) and ranks as 27th largest state by size. The Great Appalachian Valley dominates eastern New York, while Lake Champlain is the chief northern feature of the valley, which also includes the Hudson River flowing southward to the Atlantic Ocean. The rugged Adirondack Mountains, with vast tracts of wilderness, lie west of the valley. Most of the southern part of the state is on the Allegheny plateau, which rises from the southeast to the Catskill Mountains. The western section of the state is drained by the Allegheny River and rivers of the Susquehanna and Delaware systems. The Delaware River Basin Compact, signed in 1961 by New York, New Jersey, Pennsylvania, Delaware, and the federal government, regulates the utilization of water of the Delaware system. The highest elevation in New York is Mount Marcy in the Adirondacks.

New York's borders touch (clockwise from the west) two Great Lakes (Erie and Ontario, which are connected by the Niagara River); the provinces of Ontario and Quebec in Canada; Lake Champlain; three New England states (Vermont, Massachusetts, and Connecticut); the Atlantic Ocean, and two Mid-Atlantic states (New Jersey and Pennsylvania). In addition, Rhode Island shares a water border with New York.

Contrasting with New York City's urban atmosphere, the vast majority of the state is dominated by farms, forests, rivers, mountains, and lakes. New York's Adirondack Park is the largest state park in the United States. It is larger than the Yellowstone, Yosemite, Grand Canyon, Glacier and Olympic National Parks combined. New York established the first state park in the United States at Niagara Falls in 1885. Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction. The Hudson River begins with Lake Tear of the Clouds and flows south through the eastern part of the state without draining Lakes George or Champlain. Lake George empties at its north end into Lake Champlain, whose northern end extends into Canada, where it drains into the Richelieu and then the St. Lawrence Rivers. Four of New York City's five boroughs are on the three islands at the mouth of the Hudson River: Manhattan Island, Staten Island, and Brooklyn and Queens on Long Island.

"Upstate" and "Downstate" are common terms used to distinguish New York State counties north of suburban Westchester and Rockland counties, on the one hand, from the New York City metropolitan area on th other. Upstate New York typically includes the Catskill and Adirondack Mountains, the Shawangunk Ridge, the Finger Lakes and the Great Lakes in the west; and Lake Champlain, Lake George, and Oneida Lake in the northeast; and rivers such as the Delaware, Genesee, Mohawk, and Susquehanna. (A popular joke goes, "Where does Upstate begin?" "At the sign that says, 'Welcome to Yonkers'!") Central New York is the region centered around Syracuse and Utica, regions west of Syracuse are Western New York (i.e. Rochester and Buffalo), Binghamton, Elmira and west along the Pennsylvania line is the "Southern Tier," and "The North Country" is the region between the Adirondacks and the Canadian border, from the Watertown area to Plattsburgh. Residents of neighboring states and provinces may use the term "New York State" to refer to Upstate New York, to distinguish the region from New York City        Alıntıdır.
