New York State Route 15 (NY 15) is a north–south state highway located in western New York in the United States. The southern terminus of the route is officially at Interstate 390 (I-390) exit 3 south of the village of Wayland, although some signage indicating that NY 15 continues south to the northern terminus of U.S. Route 15 (US 15) in Painted Post still exists. The northern terminus of NY 15 is at an intersection with NY 31 in downtown Rochester. Outside of Monroe County, NY 15 is a rural two-lane highway. In the Rochester suburbs of Henrietta and Brighton, however, NY 15 is a major commercial strip, and the section in Rochester is a two-to-four lane street that serves commercial and residential areas.

From Lakeville north to the Rochester city limits, NY 15 is little more than an alternate route to I-390, which closely follows the route through northern Livingston County and southern Monroe County. South of Lakeville, the route is a regionally important highway that serves the villages of Livonia and Wayland and the hamlets of Conesus and Springwater. It crosses US 20 and NY 5 near Avon and overlaps with US 20A between Livonia and Lakeville. NY 15A, an easterly alternate route of NY 15, parallels its parent from Springwater north to Rochester.
