New York State Route 372 (NY 372) is an east–west state highway in southern Washington County, New York, in the United States. It extends for just under 9 miles (14 km) from an intersection with NY 22 in the village of Cambridge to a junction with NY 29 in the village of Greenwich. The route is known as Main Street inside of both villages, the most populated and developed locations on the route. Outside of the two communities, NY 372 is a rural connector traversing mostly undeveloped areas. The road was taken over by the state of New York in stages during the 1910s and 1920s and designated as NY 372 as part of the 1930 renumbering of state highways in New York.
