The Tioughnioga River /taɪ.əˈnoʊɡə/ is a 34.2-mile-long (55.0 km) tributary of the Chenango River in central New York in the United States. It drains a dissected plateau area east of the Finger Lakes at the northernmost edge of the watershed of the Susquehanna River. The name comes from a native word for "forks of the river" or "meeting of waters". The river was also called "Tiohujodha" by the Moravians. At one time it was called the Onondaga, as leading to that town, and Teyoghagoga was another early form.
