Pocantico Hills is an unincorporated hamlet in the town of Mount Pleasant, Westchester County, New York, United States, about 28 miles (45 km) north of Midtown Manhattan in New York City. It occupies the area of approximately 2.5 square miles (6.5 km2).

While official data and wider definitions vary, longtime residents consider only the houses immediately surrounding the historical Rockefeller family estate (anchored by Kykuit, the family seat built by John D. Rockefeller Sr.) to be the true Pocantico Hills. The district served by the Pocantico Hills Fire Department contains 270 households (as of 2025). The hamlet is almost completely surrounded by the Rockefeller State Park Preserve. It shares the postal code, 10591, with the nearby villages of Sleepy Hollow and Tarrytown.
