The Chitina River (/tʃɪtˈ.nʌ/ or /tʃɪ.tiːˈ.nʌ/; Ahtna Athabascan Tsedi Na’ [tʃɛ.diː.näʔ] < tsedi "copper" + na’ "river") is a 112-mile (180 km) tributary of the Copper River in the U.S. state of Alaska. It begins in the Saint Elias Mountains at the base of Chitana Glacier and flows generally northwest through the Wrangell–St. Elias National Park and Preserve to meet the larger river near Chitina.
