Out of Jimmy's Head (abbreviated as OOJH) is an American teen sitcom. It was advertised as the first Cartoon Network original series in its genre, and is based on the network's 2006 film Re-Animated. 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). It was created by Tim McKeon and Adam Pava, who were originally the writers for Foster's Home for Imaginary Friends 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 to be affected by the 2007 Writers Guild of America strike. 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 HBO Max.

Cartoon Network did not acknowledge the series again until 2018, where Golly had a cameo role in the OK K.O.! Let's Be Heroes episode, Crossover Nexus, along with a small cameo with Dolly in the 20th anniversary mural from 2012.
