Clay is a town in Onondaga County, New York, United States.

The town was named after American attorney and statesman Henry Clay.

Prior to European settlement in the area, Clay was inhabited by the Onondaga Nation, part of the Iroquois Confederacy, some of whose descendants still live in the area today.
