Joseph Henry Simon was an American comic book writer, artist, editor, and publisher. Simon created or co-created many important characters in the 1930s–1940s Golden Age of Comic Books and served as the first editor of Timely Comics, the company that would evolve into Marvel Comics.

Timely Comics is the common name for the group of corporations that was the earliest comic book arm of American publisher Martin Goodman, and the entity that would evolve by the 1960s to become Marvel Comics.
