New York State Route 19A (NY 19A) is a north–south state highway in western New York in the United States. It is an alternate route of NY 19 between the town of Hume (at the hamlet of Fillmore) and the vicinity of the village of Silver Springs. NY 19A also serves the community of Portageville and the village of Castile. The portion of NY 19A south of Portageville closely follows the Genesee River. North of Portageville, the route parallels the Southern Tier Line. NY 19A was assigned as part of the 1930 renumbering of state highways in New York.
