Western New York is the westernmost region of the state of New York. It includes the cities of Buffalo, Rochester, Niagara Falls, the surrounding suburbs, as well as the outlying rural areas of the Great Lakes lowlands, the Genesee Valley, and the Southern Tier. Some historians, scholars and others consider the Western New York border to be at the Monroe–Orleans County line. However, many in the region consider Western New York's easternmost county to be Wayne County.

Western New York consists of 12 western counties in New York State: Allegany, Cattaraugus, Chautauqua, Erie, Genesee, Orleans, Niagara, Wyoming, Monroe, Wayne, Livingston and Ontario, with a land area of 8,973 square miles (23,240 km²). Western New York can also be defined as the area of New York within the Buffalo and Rochester media markets. The Buffalo market covers the eight counties of the Holland Purchase (as well as two counties in Pennsylvania; each station varies slightly in its coverage) and the Rochester market covers from Wyoming County northeastward to Wayne County.

New York (/njuː ˈjɔrk/; locally IPA: [nɪu ˈjɔək] or [nuː ˈjɔɹk] ( listen)) is a state in the Northeastern region of the United States. New York is the 27th most extensive, the 3rd most populous, and the 7th most densely populated of the 50 United States. New York is bordered by New Jersey and Pennsylvania to the south, and by Connecticut, Massachusetts and Vermont to the east. The state has a maritime border with Rhode Island east of Long Island, as well as an international border with the Canadian provinces of Ontario to the west and north, and Quebec to the north. The state of New York is often referred to as New York State to distinguish it from New York City.

New York City, with a population of over 8.1 million, is the most populous city in the United States. Alone, it makes up over 40 percent of the population of New York state. It is known for its status as a center for finance and culture and for its status as the largest gateway for immigration to the United States. According to the U.S. Department of Commerce, New York City is also a destination of choice for many foreign visitors. Both the state and city were named for the 17th century Duke of York, James Stuart, future James II and VII of England and Scotland.

York (local ⁱ/ˈjɔːk/) is a walled city, situated at the confluence of the Rivers Ouse and Foss in North Yorkshire, England. The city has a rich heritage and has provided the backdrop to major political events throughout much of its two millennia of existence. The city offers a wealth of historic attractions, of which York Minster is the most prominent, and a variety of cultural and sporting activities.

The city was founded by the Romans in 71 AD, under the name of Eboracum. It became in turn the capital of the Roman province of Britannia Inferior, and of the kingdoms of Northumbria and Jorvik. In the Middle Ages, York grew as a major wool trading centre and became the capital of the northern ecclesiastical province of the Church of England, a role it has retained.

In the 19th century York became a hub of the railway network and a confectionery manufacturing centre. In recent decades, the economy of York has moved from being dominated by its confectionery and railway-related industries to one that provides services. The University of York and health services have become major employers, whilst tourism has become an important element of the local economy.
