New York State Route 91 (NY 91) is a north–south state highway in Central New York in the United States. The southern terminus of the route is located at an intersection with NY 13 in the Cortland County town of Truxton. Its northern terminus is located at a junction with NY 173 in the Onondaga County hamlet of Jamesville. In between, NY 91 serves the village of Fabius and the hamlet of Pompey, where it meets NY 80 and U.S. Route 20 (US 20), respectively.

NY 91 originally extended as far south as Cincinnatus and as far north as Bridgeport when it was assigned as part of the 1930 renumbering of state highways in New York. The route was truncated to its current northern terminus at Jamesville in the late 1930s and cut back to its modern southern terminus at Truxton in 1981. Most of NY 91's former routing northeast of Syracuse became NY 298 while the highway that NY 91 followed from Cincinnatus to Truxton is now maintained by Cortland County as County Route 600 (CR 600) and County Route 600A.
