Western New York (WNY) is the westernmost region of the U.S. state of New York. The eastern boundary of the region is not consistently defined by state agencies or those who call themselves "Western New Yorkers". Almost all sources agree WNY includes the cities of Buffalo, Niagara Falls, Jamestown, and the surrounding suburbs, as well as the outlying rural areas of the Great Lakes lowlands and Niagara Frontier, and Chautauqua-Alleghany (or the western Southern Tier). Many would also place Rochester and the Genesee Valley in the region while some would also include the western Finger Lakes within the region. Others would describe the latter three areas as being in a separate Finger Lakes region.
