Marvel Graphic Novel (MGN) is a line of graphic novel trade paperbacks published from 1982 to 1993 by Marvel Comics. The books were published in an oversized format, 8.5" x 11", similar to French albums. In response, DC Comics established a competitor line known as DC Graphic Novel.

A graphic novel is a long-form work of sequential art. The term graphic novel is often applied broadly, including fiction, non-fiction, and anthologized work, though this practice is highly contested by comics scholars and industry professionals. It is, at least in the United States, typically distinct from the term comic book, which is generally used for comics periodicals and trade paperbacks.
