New York State Route 13 (NY 13) is a state highway that runs mainly north–south for 152.30 miles (245.10 km) between NY 14 in Horseheads and NY 3 west of Pulaski in Central New York in the United States. In between, NY 13 intersects with Interstate 81 (I-81) in Cortland and Pulaski and meets the New York State Thruway (I-90) in Canastota. NY 13 is co-signed with several routes along its routing, most notably NY 34 and NY 96 between Newfield and Ithaca; NY 80 between DeRuyter and Cazenovia; and NY 5 between Chittenango and Canastota.

The most heavily traveled section of the route is the 50-mile (80 km) northeast–southwest section between Horseheads and Cortland. Situated midway between the two locations is the city of Ithaca; here, a small section of NY 13 follows an expressway alignment around much of the city. Much of the route, however, is a two-lane highway that passes through rural areas. When NY 13 was originally assigned in the 1920s, it extended only from Elmira to Cazenovia. It was significantly extended in 1930, stretching from Lindley in the south to Richland in the north. The southern terminus was moved back to Elmira in the 1940s and has been located at various points in the city since then.
