Out of Jimmy's Head (abbreviated as OOJH) is an American live-action animated teen sitcom created by Tim McKeon and Adam Pava for Cartoon Network. It is based on the network's 2006 film Re-Animated, and is the first live-action animated television series produced by Cartoon Network. The series was produced by Cartoon Network Studios and Brookwell McNamara Entertainment (the latter known for Disney's shows such as Even Stevens and That's So Raven). The creators, Tim McKeon and Adam Pava, were originally writers for Foster's Home for Imaginary Friends, As Told by Ginger, and The Life and Times of Juniper Lee, as well as the creators of Weighty Decisions short on Cartoon Network's Sunday Pants anthology series.

The series premiered on Cartoon Network on September 14, 2007, to coincide with the release of the Re-Animated film on DVD, and was the only network series affected by the 2007 Writers Guild of America strike. It then made its Canadian premiere on Teletoon on Saturday, September 6, 2008. It also aired on Boomerang in Australia. The U.S. run of the series ended with the airing of the series' final episode on May 29, 2008. The series never streamed on Max.

Although Renegade Animation did the pilot film's animation, due to budget and time constraints, the series' animation was produced in-house at the Cartoon Network Studios' flash division. Cartoon Network did not acknowledge the series again until 2018, where Golly had a cameo role on OK K.O.! Let's Be Heroes, in the season two episode, Crossover Nexus, along with a small cameo with Dolly and Crocko in the 20th anniversary mural from 2012.

The show received extremely negative reviews from critics and mixed reviews from audiences. Before October 4, 2023, this show was considered to be lost media, due to Cartoon Network erasing the show from all online streaming websites, including its own. The show got a DVD release exclusively in the United Kingdom, containing only the first three episodes.
