Krypto the Superdog is an American animated television series produced by Warner Bros. Animation, based on Superman's canine companion Krypto, which premiered on Cartoon Network on March 25, 2005 (exactly 50 years after his comic debut), and aired on The CW's Saturday morning block Kids' WB from September 23, 2006, until September 15, 2007. 39 episodes were produced.

A comic book series (based on the TV show) was published by DC Comics under the Johnny DC imprint, which lasted 6 issues, from 2006 to 2007.

The show was developed by producers Alan Burnett and Paul Dini, who had produced the successful Batman: The Animated Series and Superman: The Animated Series. Instead of continuing in that style, Krypto was produced in a manner reminiscent of the Hanna-Barbera shows of the 1960s to the 1980s, from the sound effects down to the animation style (veteran Hanna-Barbera designer Iwao Takamoto served as a creative consultant).
