Uncle Grandpa is an American animated television series created by Peter Browngardt for Cartoon Network that ran from September 2, 2013, to June 30, 2017.

Creator Pete Browngardt has cited the work of cartoonists Don Martin, 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.

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.

Retrospective reviews have been more positive, especially after the release of Browngardt's Looney Tunes Cartoons (which he developed), with critics and viewers alike praising its concept, humor, deranged animation and overall tone.

A double-length Christmas special, it centers on Uncle Grandpa who reluctantly agrees to disguise himself as his brother Santa Claus, after the latter character injures a leg.

[9] Conceived of by the creator of the latter series, Rebecca Sugar,[10] the episode has Uncle Grandpa teach Steven how to bear a shield from his gemstone.

One year later, a full episode based on the babies saving America from a foreign country's missile launch aired on August 20, 2015.

The Uncle Grandpa pilot was created by former Chowder storyboard artist Peter Browngardt, who first pitched the idea to Cartoon Network in 2006.

Browngardt, who grew up the youngest in a large family of eight children (his eldest brother Tom would go on to work as the show's film editor), based the character upon the various and often eccentric relatives who would often drop by and visit them, as well as aspects of his own personality.
