Western New York 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 Niagara Frontier, and Chautauqua-Alleghany.
