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) from August 22, 2005 to November 28, 2007 and on Teletoon in Canada (premiering on the latter on August 29, 2005), later airing in reruns on Boomerang around 2007. It also aired on ABC Kids in Australia. It is produced by Cookie Jar Entertainment, with animation provided by Mercury Filmworks.

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.

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.
