The Cohocton River, sometimes referred to as the Conhocton River, is a 58.5-mile-long  tributary of the Chemung River in western New York in the United States. Via the Chemung River, it is part of the Susquehanna River watershed, flowing to Chesapeake Bay. The name "Cohocton" is derived from an Iroquois term, Ga-ha-to, meaning "log floating in the water" or "trees in the water".
