J. Steven York (born 1957 in Alabama, United States) is an American science fiction and fantasy writer. York was born in rural southeast Alabama and from childhood showed a strong interest in science fiction, fantasy and space exploration. It was only a matter of time before his vivid imagination drove him to share his stories and interests in the form of writing. York also collaborated with author Dean Wesley Smith on a pair of novellas based on the Bolo stories of late science-fiction author Keith Laumer, which were published in the anthologies Old Guard and Cold Steel, from Baen Books.
