West Valley is a hamlet in the Town of Ashford in Cattaraugus County, New York, United States.

The population was 518 at the 2010 census, which lists the community as a census-designated place.

[6] Located at the intersection of Cattaraugus County Route 53 and State Route 240/County Route 32, the hamlet is home to West Valley Central School and the West Valley Demonstration Project, a nuclear cleanup facility.

Because of the presence of a school district, a telephone exchange (716–942), and a post office located in (and named after) the hamlet, many people mistake West Valley to be the name of an actual town or village.
