Robin of Earth-Two is an alternate version of the superhero Robin, 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 which had been published in the Golden Age of comic books. This allowed creators to publish comic books taking place in current continuity while being able to disregard Golden Age stories featuring Robin, solving an incongruity, as Robin had been published as a single ongoing incarnation since inception. Unlike his main counterpart, Robin is the only alter ego of Dick Grayson, who uses the title into adulthood, rather than taking on later codenames such as Nightwing or Batman. In addition, the name "Robin" is not taken on by later characters.

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.
