Gotham by Gaslight is a DC Comics one-shot by Brian Augustyn and Mike Mignola, with inks by P. Craig Russell and an introduction (written in the character of Jack the Ripper) by Robert Bloch.

The story revolves around a 19th-century version of Bruce Wayne making his debut as Batman just as Jack the Ripper has arrived in Gotham City.

It spawned two sequels, Batman: Master of the Future (1991), also written by Augustyn, with art by Eduardo Barreto, and a third book in the series, Gotham by Gaslight: The Kryptonian Age, which began publishing in June 2024.

Bruce tells Freud that he has a recurring dream in which he recalls the murder of his parents and decides he must return to Gotham City.

Just one day before the execution, Bruce learns the Ripper's identity by discovering he had the skill of a surgeon and used a knife that belonged to the medical group who worked with his father.

Having brought his parents' murderer to justice, he has come to regard Batman as a childish fancy, and intends to devote his life to more serious pursuits.

With the police fully occupied, Julie runs into the burning pavilion to rescue a small girl, but both of them are trapped by falling debris.

The two men engage in a brutal rapier duel that disables LeRoi's robotic pilot "Antonio", causing the airship to drift off course and become unstable.

Two years later, the 68-page sequel Batman: Master of the Future — also written by Augustyn, but with art by Eduardo Barreto — was released, this time officially labelled as an Elseworlds publication.

The two stories have been collected into a trade paperback: IGN Comics ranked Gotham by Gaslight #11 on a list of the 25 greatest Batman graphic novels, saying that the comic is "as taut and well-conceived a graphic novel as you can find — Elseworlds or otherwise; quite simply, no other Elseworlds tale has managed such a brilliant concept nor executed it so perfectly".

Gotham by Gaslight was not the highest-ranking Elseworlds story on the list, as Batman & Dracula: Red Rain ranked higher at #9.

[3] The story saw Bob the Monitor accompany Jason Todd, Donna Troy, and Kyle Rayner (the latter three inhabitants of "New Earth") through the Multiverse in search of multiuniversal counterparts to Ray Palmer.

Their search would take them to worlds populated by characters from other Elseworlds stories, including those seen in the Batman & Dracula trilogy (Earth-43) and Superman: Red Son (Earth-30).
