Ridge Road is a 121.5-mile (195.5 km) east–west road that traverses four counties in Upstate New York in the United States. The road begins adjacent to the Niagara River at an intersection with Water Street in the village of Lewiston, Niagara County, and passes through several towns, villages, and the city of Rochester before arriving at its eastern terminus at a junction with New York State Route 370 (NY 370) southwest of Red Creek, Wayne County. It is named for the rise atop which the road was built, a mound of sand and gravel that was formed when it was the shoreline of ancient Glacial Lake Iroquois. The ridge is often confused with the nearby Niagara Escarpment, which is much taller, geologic in origin, and lies a few miles to the south.

Lewiston is a village in Niagara County, New York, United States. The population was 2,701 at the 2010 census. The village is named after Morgan Lewis, an early 19th-century governor of New York. It is part of the Buffalo–Niagara Falls Metropolitan Statistical Area.
