James Hendryx (1880-1963) was a Minnesota-born American author of western fiction. He worked as a journalist in Ohio for the Cincinnati Enquirer before turning to fiction writing. From 1915 onward, he published steadily in both the flourishing pulp magazine market, as well as the book market. He published more than 40 novels books and hundreds of short stories during his 50-year career.

He specialized in the western genre, but had a broad interpretation of what constitutes Western. Ultimately he specialized in the Canadian West. He wrote several series, including Corporal Downey of the North West Mounted Police, Connie Morgan, and the Halfaday Creek series.
