The Cosna River (Lower Tanana: K'osno) is a 44-mile (71 km) tributary of the Tanana River in the central part of the U.S. state of Alaska. It flows northward from the Bitzshtini Mountains into the Tanana west (downstream) of Manley Hot Springs.
In 1899, Lieutenant J. S. Herron attributed the name to the Tanana peoples living in the area. However linguist William Bright, citing the Koyukon Athabascan Dictionary a century later, attributed the name to the Koyukon words kk'os, schist rock, combined with no', river.
