William Roderick James (June 6, 1892 – September 3, 1942) was a Canadian-American artist and writer of the American West. He is known for writing Smoky the Cowhorse, for which he won the 1927 Newbery Medal, and numerous "cowboy" stories for adults and children. His artwork, which predominantly involved cowboy and rodeo scenes, followed "in the tradition of Charles Russell", and much of it was used to illustrate his books. In 1992, he was inducted into the Hall of Great Westerners of the National Cowboy & Western Heritage Museum.
