Kaaterskill High Peak is one of the Catskill Mountains, located in the Town of Hunter in Greene County, New York, United States. It was once believed to be the highest peak in the entire range, but its summit, at 3,655 feet in elevation, places it only 23rd among the Catskill High Peaks. It is, however, the fourth most prominent peak in the range. Due to its situation as the easternmost High Peak, its summit is just outside the watersheds of New York City's reservoirs in the region.
