DC Universe Presents is the name of two DC Comics publications. The first was part of the UK 'Collector's Edition' line of DC Comics published by Titan Magazines. Beginning March 2007, it was originally titled Superman Legends and was published alongside Batman Legends. Titan also later released several other DC comics following on from the success of Superman and Batman Legends. The book was retitled as DC Universe Presents at issue 33 but continued the issue count of Superman Legends, despite the change in title and in some of its content. The title reprinted DC Comics from the United States including Justice League, Superman and Green Lantern and was edited by Mark McKenzie-Ray.

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.
