Gotham by Gaslight is a DC Comics one-shot by Brian Augustyn and Mike Mignola, with inks by P. Craig Russell. 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.

Brian Augustyn was an American comic book editor and writer. He often worked as editor or co-writer with writer Mark Waid, such as on The Flash in the 1990s. He wrote Gotham by Gaslight – which imagines Batman tracking Jack the Ripper – the prototype of DC's Elseworlds imprint, which featured versions of their characters in alternate settings.
