Superman/Batman

Superman/Batman is a monthly American comic book series published by DC Comics that features the publisher's two most popular superheroes: Superman and Batman. Superman/Batman premiered in August 2003, an update of the previous series, World's Finest Comics (1941–1986), in which Superman and Batman regularly joined forces.

Superman/Batman explores the camaraderie, antagonism, and friendship between its title characters. Jeph Loeb, the series' first writer, introduced a dual-narrator technique to present the characters' often opposing viewpoints and estimations of each other, which subsequent series writers have maintained. Prior to the events of Batman and the Outsiders #1 (1983), the two iconic characters were depicted as the best of friends. Frank Miller's landmark series The Dark Knight Returns subsequently depicted the heroes as adversaries in a future timeline. This dynamic became standard with John Byrne's The Man of Steel, a Superman reboot published in 1986.

After the first 13 issues, most of the story arcs were independent and self-contained from the ongoing or crossover storylines in the other Batman and Superman comic titles. Superman/Batman #26, Loeb's final issue, features a story written by his son Sam, who died from cancer prior to its release. Twenty-six writers and artists who knew Sam worked on the issue, donating fees and royalties to the Sam Loeb College Scholarship Fund.

As part of The New 52, a series titled Batman/Superman was released from 2013 to 2016. A second Batman/Superman series was released in August 2019, with issue #16 as part of DC's Infinite Frontier.

A new ongoing series by Mark Waid titled Batman/Superman: World's Finest was released in March 2022.
