Superman Unchained is a 2013–14 comic book miniseries published by DC Comics, and featuring the superhero Superman, as he encounters a powerful new opponent named W.R.A.I.T.H. who may be his match. Originally billed as ongoing, the series launched in June 2013 to mark Superman's 75th anniversary, two days before the release of the feature film Man of Steel, and ran for a year and a half. A continuation of DC's 2011 relaunch of its entire monthly line of books known as The New 52, the series was written by Scott Snyder and illustrated by Jim Lee and Scott Williams. The entire story received largely positive reviews.

The New 52 was the 2011 revamp and relaunch by DC Comics of its entire line of ongoing monthly superhero comic books. Following the conclusion of the "Flashpoint" crossover storyline, DC cancelled all its existing titles and debuted 52 new series in September 2011. Among the renumbered series were Action Comics and Detective Comics, which had retained their original numbering since the 1930s.
