Cox, Ross, 1793–1853, American fur trader. He joined John Jacob Astor's Pacific Fur Company in 1811 and went to the Astoria post on the supply ship Beaver. He was active in the trade in the Columbia river valley, entering the employ of the North West Company after Astoria was sold to that firm. His Adventures on the Columbia River (1831) is an entertaining as well as valuable historical source.
