Arthur Kelvin Barnes (1909-1969) was an American science fiction author. Barnes wrote mostly for pulp magazines in the 1930s and 1940s.

Barnes was most noted for his vivid and believable portrayals of alien life. As such, he is compared to Stanley G. Weinbaum. Before Barnes (and Weinbaum), SF writers usually portrayed aliens as earth-like monsters, with little originality.
