The Batman of Earth-Two is an alternate version of the superhero Batman, who appears in American comic books published by DC Comics. The character was introduced after DC Comics created Earth-Two, a parallel world that was retroactively established as the home of characters whose adventures had been published in the Golden Age of comic books. This provided justification within the fictional world of Batman stories for DC Comics publishing Batman comic books that disregarded the character's Golden Age stories, as Batman had been presented as a single ongoing incarnation of the character since his earliest stories were published.

Earth-Two is a setting for stories appearing in American comic books published by DC Comics. First appearing in The Flash #123 (1961), Earth-Two was created to explain differences between the original Golden Age and then-current Silver Age versions of characters such as the Flash, and how the current (Earth-One) versions could appear in stories alongside earlier versions of the same character concepts. Earth-Two includes DC Golden Age heroes, including the Justice Society of America, whose careers began at the dawn of World War II, concurrently with their first appearances in comics. Earth-Two, along with the four other surviving Earths of the DC Multiverse, were merged into one in the 1985 miniseries Crisis on Infinite Earths. However, following the events of Infinite Crisis, the Multiverse was reborn, although the subsequent Earth-Two was not the same as its pre-Crisis equivalent.
