Brian Moncrieff Lewis (3 June 1929 – 4 December 1978) was a British science fiction illustrator, comics artist, and animator. In the 1950s, he illustrated covers for pulp magazines like New Worlds, Science Fantasy, and Science Fiction Adventures. In the 1960s, he drew adventure comic strips for Tiger, Boys' World, Hurricane, and Eagle. He also used a more cartoony style to draw humor comic strips for Wham!, Smash, Cor!!, and Buster. In the 1970s, Lewis focused on comics adaptations of television and horror film properties.
