Stephen Youll (born June 8, 1965 in Hartlepool, England) is a science fiction artist. He got his start in the genre when his work, done in conjunction with his twin brother Paul, was seen in 1987 at the 45th World Science Fiction Convention in Brighton, England. His first commission, a collaboration with Paul, was for the cover painting for Emerald Eyes by Daniel Keys Moran that was published by Bantam Books. The brothers continued to work together until Stephen moved to the United States.
