The Chenango River is a 140 km-long tributary of the Susquehanna River in central New York in the United States. It drains a dissected plateau area in upstate New York at the northern end of the Susquehanna watershed.
Named after the Oneida word for bull thistle, in the 19th century the Chenango furnished a critical link in the canal system of the northeastern United States. The Chenango Canal, built from 1836–1837 between Utica and Binghamton, connected the Erie Canal in the north to the Susquehanna River. The canal was rendered obsolete by railroads and was abandoned in 1878.
Flooding is often a concern during the spring and fall.
