New York State Route 136 (NY 136) is a state highway within the town of North Greenbush in Rensselaer County, New York, in the United States. It begins at an intersection with U.S. Route 4 (US 4) just south of Troy and ends at a junction with NY 150 in the hamlet of Wynantskill. NY 136 provides access to Hudson Valley Community College, located in an otherwise residential area of suburban Troy. The route was assigned in the late 1930s as a connector between US 4 and Winter Street, then part of NY 40. NY 136 was extended to its current length in 1980.

U.S. Route 4 (US 4) is a part of the United States Numbered Highway System that runs from East Greenbush, New York, to Portsmouth, New Hampshire. In the U.S. state of New York, US 4 extends 79.67 miles (128.22 km) from an intersection with US 9 and US 20 in East Greenbush to the Vermont state line northeast of Whitehall. While the remainder of US 4 east of New York is an east–west route, US 4 in New York is signed north–south due to the alignment the route takes through the state. The portion of the route between Waterford and Whitehall is part of the Lakes to Locks Passage, an All-American Road.
