Hallenbeck Hill is a mountain in Greene County, New York, in the Catskill Mountains southeast of West Athens. It is part of a cluster of nearby elevations, with Potic Mountain to the west-northwest, Kykuit to the southwest, and Flint Mine Hill to the north. In this local Catskill setting, it stands as a named summit in the hills of eastern New York, identified chiefly through its relationship to the surrounding mountains and to nearby West Athens.
