New York State Route 178 (NY 178) is an east–west state highway in Jefferson County, New York, in the United States. It extends for 10.23 miles (16.46 km) from an intersection with NY 3 by Aspinwell Corners in the town of Henderson to a junction with U.S. Route 11 (US 11) in the village of Adams. NY 178 meets Interstate 81 (I-81) at exit 41 0.5 miles (0.8 km) west of its junction with US 11. When NY 178 was assigned in the 1930 renumbering of state highways in New York, it continued east along modern County Route 189 (CR 189) to NY 177 in Rodman. This extension was eliminated in 1979. From the early 1930s to the late 1960s, NY 178 also continued west toward Lake Ontario on what is now County Route 178.
CR 178 begins at an intersection with Snowshoe Road and Military Road near the shores of Lake Ontario. The highway progresses to the southeast along farmlands heading through Cedar Cove Road and Harmony Harbor. A short distance later, CR 178 enters the community of Hungerford Corners, where the right-of-way merges with Lighthouse Road. The highway continues eastward, crossing over a tributary of Lake Ontario as Military Road. The route passes to the south of Henderson Harbor, where it intersects with CR 123. A short distance later, CR 178 intersects with NY 3, where maintenance of the highway turns over to the New York State Department of Transportation and CR 178 becomes NY 178.
