Charles William Rotsler (July 3, 1926 – October 18, 1997) was an American artist, cartoonist, pornographer and science fiction author.

Rotsler's papers including dozens of matted color drawings, unpublished manuscripts and sketchbooks of original artwork are part of the Eaton Collection at University of California, Riverside.

[8] Because of Adam Film Quarterly's success, Rotsler began using pseudonyms for his appearances including "Shannon Carse", "Cord Heller", "Clay McCord", and "Merrill Dakota".

"[10] Rotsler wrote, directed, or acted in some two dozen pornographic films during his career with Boxoffice International Pictures.

He also wrote Contemporary Erotic Cinema in 1973, published by Ballantine and Penthouse, about pornographic movies from an aesthetic point of view.

"[18] Through his illustrations Rotsler also helped perpetuate the image of science fiction fans wearing propeller beanies.

[19] As an author, Rotsler's best-known story, "Patron of the Arts" (1972), was a finalist for the Hugo and Nebula award for best novelette; it was expanded to novel length in 1974 under the same title.
