New York State Route 90 (NY 90) is a north–south state highway in the Finger Lakes region of New York in the United States. All but five of the route's 53 miles (85 km) are located in Cayuga County, with the remaining 5 miles (8 km) situated in Cortland County. The southern terminus of the route is at an intersection with U.S. Route 11 (US 11) and NY 41 in the village of Homer. Its northern terminus is at a junction with NY 31 in the town of Montezuma. Although the route is signed as north–south, the portion of NY 90 from King Ferry to Homer follows an east–west alignment.

It is not to be confused with Interstate 90 (I-90), which also passes through Montezuma. The two 90s in fact cross, the only time when two same numbered highways intersect in the state, but there is no access between them.
