The Ratcatcher (Otis Flannegan) is a character appearing in American comic books and other media published by DC Comics, primarily as an enemy of Batman. He belongs to the collective of adversaries that make up the Dark Knight's rogues gallery. Once an actual rat-catcher in Gotham City, Flannegan sank into a life of crime. Calling himself the Ratcatcher because of his special ability to communicate with and train rats, Flannegan has used his minions to plague Gotham on more than one occasion by unleashing hordes of the vermin.

A female version of the character named Cleo Cazo / Ratcatcher 2 appears in the DC Extended Universe film The Suicide Squad (2021), portrayed by Daniela Melchior. Taika Waititi portrays the first Ratcatcher, Cleo's father.
