Hush (Thomas Elliot) is a supervillain appearing in American comic books published by DC Comics. Created by Jeph Loeb and Jim Lee, the character first appeared in Batman #609 in January 2003 as part of the twelve-issue storyline Batman: Hush. Hush's background is parallel to the superhero Batman, and he serves as a criminal foil to him, as an example of what Batman could have been if he came from an abusive family and had used his abilities and resources for malice. He belongs to the collective of adversaries that make up his rogues gallery.

Thomas "Tommy" Elliot was a childhood friend of Bruce Wayne who attempts to murder his own parents and inherit their massive fortune. His plan fails when Bruce's father, Dr. Thomas Wayne, saves his mother's life, beginning his grudge against the Waynes. Tommy grows up to become a gifted neurosurgeon and, out of jealous resentment, allies with the Riddler to ruin Bruce's life upon discovering that he is Batman. Wrapping his face in bandages to conceal his identity, Tommy becomes a manipulative criminal mastermind called "Hush" to seek revenge against his former friend.

The character has been adapted from the comics into numerous forms of media, having been portrayed in live-action television by Cole Vallis and Gordon Winarick in Gotham, and by Gabriel Mann and Warren Christie in Batwoman. Kevin Conroy voiced Hush in the Batman: Arkham video game series.
