Superfolks (also Super-Folks in its original cover art) is a 1977 novel by Robert Mayer (hb ISBN 0-207-95814-9, pb ISBN 0-417-05460-2). The novel satirizes the superhero and comic book genres, and was aimed at a more adult audience than those genres typically attracted.
Superfolks also examines comic book conventions and clichés from a more serious, "literary" perspective. The novel was influential on many writers of superhero comic books in the 1980s and 1990s, notably Kurt Busiek and Grant Morrison, the latter of whom brought the novel back to prominence in 1990 when he suggested that it had been a major influence on Alan Moore's Watchmen, Marvelman, and Superman: Whatever Happened to the Man of Tomorrow?, a claim Moore has generally downplayed.
