Batman: Legends of the Dark Knight, often simply called Legends of the Dark Knight, is the name of several DC comic books featuring Batman. The original series launched in 1989 as the third major monthly Batman title, following the popularity of Tim Burton's 1989 film Batman. Many of the stories follow the tone of Frank Miller's Batman: Year One. The series differed from other Batman titles of the time. The creative team rotated with every story arc and the stories stood alone, unlike the inter-connected nature of other Batman comics. Initially the title ran stories contained to five issues, often with more mature topics and sensibilities than the other Batman titles. After issue #20, the number of issues for each story began to vary and occasionally tied into crossover events.

Batman: Year One is an American comic book story arc written by Frank Miller and illustrated by David Mazzucchelli. Year One was originally published by DC Comics in Batman #404–407 in 1987. There have been several reprints of the story: a hardcover, multiple trade paperbacks, several deluxe editions in hardcover and paperback format, and an Absolute Edition. Year One was also adapted into an animated feature in 2011, after efforts to adapt it into a live-action film were cancelled following the failure of 1997's Batman & Robin.
