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 other Cartoon Network shows such as Foster's Home for Imaginary Friends and The Life and Times of Juniper Lee, before creating Weighty Decisions, a short on the network's Sunday Pants anthology series. They were also writers on the Nickelodeon animated series, As Told by Ginger.

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 series on the network to be 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 Cartoon Network Studios through their 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.
