The catch-all term adult comics typically denotes comic books, comic magazines, comic strips or graphic novels that are marketed either mainly or strictly towards adult readers. This can be because they contain material that could be considered thematically inappropriate for children, including vulgarity, morally questionable actions, disturbing imagery, and sexually explicit material.

Fantagraphics is an American publisher of alternative comics, classic comic strip anthologies, manga, magazines, graphic novels, and (formerly) the erotic Eros Comix imprint.
