Old Albany Post Road is a 6.6-mile (10.6 km) dirt road in Philipstown, New York, one of the oldest unpaved roads still in use in the United States. It runs mostly north-south through the southeastern corner of the town, near the Putnam Valley town line. Starting from an intersection with Sprout Brook Road at Continental Village just north of the Putnam-Westchester county line, it ends at an oblique junction with US 9 east of Garrison.
