Ghost World is a comic book written and illustrated by Daniel Clowes. It was originally serial (Serial (literature))ized in issues #11 through #18 (June 1993 to March 1997) of Clowess comic book series Eightball (Eightball (comic book)), and was first published in book form in 1997 by Fantagraphics Books. A commercial and critical success, it was very popular with teenage audiences on its initial release and developed into a cult classic. The book has been reprinted in multiple editions and was the basis for the 2001 feature film of the same name.

Ghost World follows the day-to-day lives of best friends Enid Coleslaw (formerly "Cohn") and Rebecca Doppelmeyer, two cynical, pseudo-intellectual and intermittently witty teenage girls recently graduated from high school in the early 1990s. They spend their days wandering aimlessly around their unnamed American (United States) town, criticizing popular culture and the people they encounter while wondering what they will do for the rest of their days. As the comic progresses and Enid and Rebecca make the transition into adulthood, the two develop tensions and drift apart.

A darkly written comic, with intermittently sombre explorations of friendship and modern life, Ghost World has become renowned for its frank treatment of adolescence. The comics success led to a movie adaptation of the same name (Ghost World (film)), released in 2001 to critical acclaim and numerous nominations, including an Academy Award for Writing Adapted Screenplay, written by Clowes.
