Uncle Grandpa is an American animated surreal comedy television series created by Peter Browngardt for Cartoon Network that ran from September 2, 2013, to June 30, 2017. It is based on Browngardt's animated short of the same name from The Cartoonstitute. Uncle Grandpa is also a spin-off of Secret Mountain Fort Awesome, which was in turn a spin-off of The Cartoonstitute short. It was produced by Cartoon Network Studios.

The show is a surreal adventure comedy that relies extensively on visual gags and catchphrases. Creator Pete Browngardt has cited the work of cartoonists Virgil Partch, Don Martin, Harvey Kurtzman, Gary Larson, and Robert Crumb, as well as Golden Age–era animators such as Tex Avery and Max Fleischer when it came to developing the style of the show. Browngardt also credited John Kricfalusi for his works. Each 11-minute episode is presented in a unique format, consisting of a main seven to nine-minute story, some short bumpers typically composed of a quick visual joke, and an original short that focuses on the show's side characters.

Cartoon Network renewed the series for the fourth and fifth seasons: first splitting the second season (of 52 episodes) into two halves, which respectively became the second and third season, then dividing in half the already announced third season into the fourth and fifth season (of 26 and 23 episodes, respectively), which served as the final seasons.

The series premiered on Cartoon Network on September 2, 2013. While the pilot was nominated in 2010 for a Primetime Emmy Award in the category of Outstanding Short-Format Animated Program, the show itself was awarded in 2014 for the work of Nick Edwards in the category of Outstanding Individual in Animation. Kevin Michael Richardson was also nominated for a Annie Award in 2016 in the category of Best Voice Acting for an Animated TV/Broadcast Production for his work as Mr. Gus in the show. The show on itself received mixed reviews from critics by the time of its release, with praise toward the show's animation and visual humor, while also receiving criticism for its pacing. Retrospective reviews have been more positive, especially after the release of Browngardt's Looney Tunes Cartoons, with critics and viewers alike praising its concept, humor, deranged animation and overall tone.

Plot The series centers on Uncle Grandpa, a comically dumb, yet magical man who claims to be the uncle and grandpa of everyone in the world. He travels in a large RV and appears without warning in the lives of children who are facing personal problems. These problems are often simple at first, such as fear, insecurity, or confusion. Uncle Grandpa attempts to help, though his methods are chaotic and illogical.

Uncle Grandpa is joined by several regular companions. These include Mr. Gus, an anthropomorphic dinosaur who often acts as the voice of reason. Pizza Steve is a loud, arrogant slice of pizza who believes he is extremely cool. Belly Bag is a fanny pack worn by Uncle Grandpa that can produce almost any object. Giant Realistic Flying Tiger also appears as a recurring character and serves as the mode of transportation for the group.

Episodes usually follow a loose structure. Uncle Grandpa arrives, causes disorder, and eventually resolves the child's problem in an unexpected way. The resolution often comes through surreal events rather than clear lessons. The show does not follow continuity. Each episode stands alone, and events reset afterward.

The humor relies on absurdism, slapstick, visual gags, and meta jokes. The series frequently breaks the fourth wall and ignores normal rules of time, space, and logic. Animation styles may change within episodes for comedic effect.
