New York State Route 9M (NY 9M) was a state highway in Warren County, New York, in the United States. It was a spur route of U.S. Route 9 (US 9) that largely followed the eastern bank of the Schroon River. The southern terminus of the route was at NY 8 in the town of Horicon near the hamlet of Starbuckville. Its northern terminus was at US 9 in the Chester hamlet of Pottersville. NY 9M was known as East Schroon River Road and Glendale Road and crossed over the southern tip of Schroon Lake.

NY 9M was assigned c. 1931 to what had been designated as legislative Route 22-c from 1913 to 1921. It lasted for less than a decade as it was removed c. 1939. Its former routing is now maintained by Warren County as part of three county routes, namely County Route 55 (CR 55), CR 62, and County Route 64.

NY 9M began at an intersection with NY 8 (now CR 53) north of the hamlet of Starbuckville in the town of Horicon. The route followed Valentine Pond Road north for a negligible distance, then progressed westward along the eastern bank of the Schroon River on East Schroon River Road. Across the river, Carl Turner Road, a locally maintained highway, followed a routing parallel to that of NY 9M on the other shore. Both roads gradually curved northward, mirroring a similar turn in the river's course. Carl Turner Road came to an end here; however, NY 9M continued on. Near a junction with modern-day Short Street, NY 9M began to deviate from the river.
