Alfred Thaddeus Crane Pennyworth is a fictional character appearing in American comic books published by DC Comics, most commonly in association with the superhero Batman.

Pennyworth is depicted as Bruce Wayne's loyal and tireless butler, legal guardian, best friend, aide-de-camp, and surrogate father figure following the murders of Thomas and Martha Wayne. As a classically trained British Butler and an ex-Special Operations Executive operative of honor and ethics with connections within the intelligence community, he has been called "Batman's batman". He serves as Bruce's moral anchor while providing comic relief with his sarcastic and cynical attitude. A vital part of the Batman mythos, Alfred was nominated for the Wizard Fan Award for Favorite Supporting Male Character in 1994.

In non-comics media, the character has been portrayed in live-action and voiced by actors William Austin, Eric Wilton, Michael Gough, Michael Caine, Jeremy Irons, Douglas Hodge, and Andy Serkis on film, and by Alan Napier, Efrem Zimbalist Jr., Ian Abercrombie, David McCallum, and Sean Pertwee on television, among others. Ralph Fiennes provided the voice of Alfred in the animated Lego Movie franchise, and Martin Jarvis voiced the character in the Batman: Arkham video game series. A young version of Pertwee's Alfred, played by Jack Bannon, depicts him before he became the butler to the Wayne family in the television series Pennyworth.
