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.

In comics studies, sequential art is a term proposed by comics artist Will Eisner to describe art forms that use images deployed in a specific order for the purpose of graphic storytelling or conveying information. The best-known example of sequential art is comics.
