New York State Route 280 (NY 280) is an 11.59-mile (18.65 km) long north–south state highway in rural Cattaraugus County, New York, in the United States. The southern terminus of the route is at the Pennsylvania state line in South Valley, where it becomes Pennsylvania Route 346 (PA 346). The northern terminus is at exit 18 on the Southern Tier Expressway (Interstate 86 or I-86 and NY 17) in Coldspring, west of Salamanca. NY 280 follows both the eastern edge of the Allegheny Reservoir and the western boundary of Allegany State Park for its entire length.
When NY 280 was originally assigned as part of the 1930 renumbering of state highways in New York, it was little more than a short spur route off of NY 17 that followed the Allegheny River south to the hamlet of Quaker Bridge. In 1965, the Kinzua Dam was completed, leading to the creation of the Allegheny Reservoir and the inundation of much of NY 280. As a result, the route was shifted onto a new alignment that was constructed along the eastern edge of the reservoir.
