The Buckland River (Kaŋiq in Inupiaq) is a stream, 67 mi long, in the U.S. state of Alaska. It flows northwest to the Chukchi Sea at Eschscholtz Bay, 40 mi southwest of Selawik in the Northwest Arctic Borough. Naval officer Frederick William Beechey named the river in 1826 for a geology professor at the University of Oxford in England. Other 19th-century names for the river included Russian translations of the Inuit as Kanyk and the Koyukon Indian as Kotsokhotana. Another translation of the Inuit was Kung-uk.
