The Cosna River[pronunciation?] is a 44-mile (71 km) tributary of the Tanana River in the central part of the U.S. state of Alaska.[3] It flows northward from the Bitzshtini Mountains into the Tanana west (downstream) of Manley Hot Springs.[4]

In 1899, Lieutenant J. S. Herron attributed the name to the Tanana peoples living in the area.[2] However, a century later linguist William Bright, citing the Koyukon Athabascan Dictionary, attributed the name to the Koyukon words kk' os, schist rock, combined with no', river.[5]
