Wildcat Mountain is a summit in the Catskill Mountains of Ulster County, New York, east-southeast of Frost Valley. It stands within a tightly grouped mountain area, with Hemlock Mountain to the northeast, Van Wyck Mountain to the southeast, and Fir Mountain to the north. Its significance here lies in its place within this cluster of Catskill peaks and in how it is identified through its relationship to Frost Valley and the surrounding mountains.
