New York State Route 117 (NY 117) is a 15.57-mile (25.06 km) state highway in Westchester County, New York, in the United States. The southern terminus of the route is at an intersection with U.S. Route 9 (US 9) north of the village of Sleepy Hollow. The northern terminus is at an interchange with the Saw Mill River Parkway south of Katonah, a hamlet in the town of Bedford. NY 117 meets the Taconic State Parkway in Pleasantville and parallels the Saw Mill Parkway from Pleasantville to Bedford.
NY 117 was assigned as part of the 1930 renumbering of state highways in New York and originally extended from Tarrytown to Katonah. The Tarrytown–Pleasantville portion of NY 117 passed through Kykuit, the estate of the Rockefeller family. Construction on a new limited-access highway bypassing the estate to the north began in the late 1960s and was completed in 1971, at which time NY 117 was realigned to follow the highway. Another highway bypassing Katonah was built in the early 1990s and opened c. 1992 as a realignment of NY 117.
