New York State Route 131 (NY 131) is a 12.45-mile (20.04 km) long state highway in St. Lawrence County, New York, United States. It serves as a coastal alternate route to NY 37, going around the village of Massena instead of through it. NY 131 leaves NY 37 in the town of Louisville and rejoins it in the town of Massena. Town Line Road, a county-maintained highway straddling the Louisville Massena town line, serves as a connector between NY 131 and Massena village.
