New York State Route 170 (NY 170) is a north–south state highway in Herkimer County, New York, in the United States. It runs from NY 169 in the city of Little Falls to NY 29 in the town of Fairfield. It has only one other junction with a signed state highway, that being NY 170A, its spur route in the town of Fairfield. NY 170 was assigned as part of the 1930 renumbering of state highways in New York and has not been altered since.

NY 170 begins at an intersection with NY 169 (West Monroe and North Ann streets) in the city of Little Falls. The route proceeds eastward through the north end of Little Falls along the two-lane East Monroe Street, traversing several blocks of homes until the intersection with Moreland Street. At Moreland Street, NY 170 winds northward on a gradual bend up a hill west of Moreland Park. The route then gradually curves northwest, passing Holy Trinity Cemetery and an intersection with the western terminus of Burrell Road (unsigned County Route 9 or CR 9). NY 170 passes a large complex in Little Falls before turning north past the Little Falls Municipal Golf Course. Continuing north through Little Falls, the route intersects with Sabin Road and Dise Road (CR 159) at a four-way junction.

Still in the town of Little Falls, NY 170 crosses under power lines, crossing an intersection with Top Notch Road (CR 126) and Yellow Church Road (CR 92). At this intersection, the route crosses into the town of Fairfield, where two-lane rural roadway continues north, winding past several farms in Fairfield. The route soon intersects with the terminus of NY 170A, a short spur route of NY 170. At NY 170A, NY 170 bends northwest, crossing past several farms and an intersection with Castle Road (CR 7). The surroundings of NY 170 remain unchanged as the road continues northwest to an intersection with NY 29 in Fairfield that serves as NY 170's north end.
