Kingdom Come is a four-issue comic book mini-series published in 1996 by DC Comics under their Elseworlds imprint. It was written by Alex Ross and Mark Waid and painted in gouache by Ross, who also developed the concept from an original idea. This Elseworlds story is set in a future that deals with a growing conflict between "traditional" superheroes, such as Superman, Wonder Woman, and the Justice League, and a growing population of largely amoral and dangerously irresponsible new vigilantes, in many cases the offspring of the traditional heroes. Between these two groups is Batman and his assembled team, who attempt to contain the escalating disaster, foil the machinations of Lex Luthor, and prevent a world-ending superhuman war.

Nelson Alexander "Alex" Ross is an American comic book writer/artist known primarily for his painted interiors, covers and design work.
