New York State Route 890 (NY 890) is a 1.00-mile (1.61 km) long state highway located northwest of downtown Schenectady in the Capital District of New York in the United States. Although the route runs north–south, it is signed as east–west to match the posted direction of Interstate 890 (I-890), of which NY 890 is an extension. The western terminus of the route is at an intersection with NY 5 in the town of Glenville, and its eastern terminus is at an interchange with I-890 in the town of Rotterdam, where NY 890 becomes I-890 and continues east into Downtown Schenectady.
