Yin Yang Yo! is a Flash animated television series created by Bob Boyle for Jetix. Produced by Jetix Animation Concepts as the third Jetix original series, it first aired on August 26, 2006, as a sneak peek and premiered on September 4, 2006, in the United States. The show debuted on Jetix in the United Kingdom on February 5, 2007, after a sneak peek preview on January 27, 2007, while making its Canadian television premiere on Family Channel on March 25, 2007. The series is supplied with writers and animators' staff associated with The Fairly OddParents, 6teen, Clone High, Wow! Wow! Wubbzy! and Danny Phantom. Head writer Steve Marmel, an anime fan, took an inspiration from various anime like FLCL and anime-influenced shows such as Teen Titans. The series centers on two anthropomorphic twin rabbits named Yin and Yang, and their sensei-like panda figure named Yo, a master of fictional mystical martial arts called Woo Foo.

During 2007, this show was nominated for British Academy Children's Award by the BAFTA in the International category, but lost to Nickelodeon's SpongeBob SquarePants. From its launch on June 1, 2011, to late 2012, Disney XD Canada aired reruns of the series.
