Gerald McBoing-Boing is a Flash-animated children's television series based on the 1950 animated short film Gerald McBoing-Boing, that aired on Cartoon Network in the United States (as part of their then-Tickle-U programming block) for its first 14 episodes from August 22, 2005 to 2006. The series aired on Teletoon in Canada, premiering on August 29, 2005 and ending its first season on November 28, 2007. It also aired on ABC Kids in Australia. It was set to later air in reruns on Boomerang around 2007.

It uses the same basic art style as the original except more detailed: each 11-minute episode features a series of vignettes with Gerald, of what the "fantasy tales" are done in Seussian rhyme. Sound checks, gags, and "real-life" portions of the show are also included. Gerald still only makes sounds (and, unlike the UPA specials, is actually praised for it), but he now has two speaking friends, Janine and Jacob, as well as a dog named Burp, who only burps (accompanied by someone, usually Gerald's mother, saying "excuse me" afterwards). Gerald's parents (names unknown) also fill out the regular cast. It is produced by Cookie Jar Entertainment, with animation provided by Mercury Filmworks.

Each episode was directed by Robin Budd and story edited/written by John Derevlany. The music and score for the series was composed by Ray Parker and Tom Szczesniak. 26 episodes (52 segments) were produced for the first season. The second season first premiered on Teletoon from early episodes in 2008 and the channel later premiered the rest on January 20, 2010 as part of a long-running Gerald McBoing Boing-themed day-a-thon. This marathon aired before Total Drama Island, of which a lost commercial aired that same day had Chris McLean announcing the marathon.
