New York State Route 11A (NY 11A) is a 13.11-mile (21.10 km) state highway in Onondaga County, New York, in the United States. It is an alternate route of U.S. Route 11 (US 11), beginning at an intersection with NY 80 in the town of Tully just west of where NY 80 crosses US 11. The route heads to the north, running along Onondaga Creek and passing through the Onondaga Reservation before ending at a junction with US 11 in Nedrow, a neighborhood just south of the Syracuse city limits. NY 11A was assigned as part of the 1930 renumbering of state highways in New York and has not been substantially altered since.
