The Marvelous Misadventures of Flapjack is an American animated television series created by Thurop Van Orman for Cartoon Network. The series premiered on June 5, 2008, and ended on August 31, 2010. It stars Van Orman as the voice of Flapjack, a naïve young boy who was raised by a whale named Bubbie and is mentored by a crusty old pirate named Captain K'nuckles. Together the trio spend their days in Stormalong Harbor, where most of the show takes place, while getting into mishaps on the search for the elusive Candied Island.

Van Orman, who pitched the idea to Cartoon Network as early as 2001, incorporated his own dreams of marine adventures, acquired while living in Florida as a boy, into the series. During its run, Flapjack received two Primetime Emmy Award nominations, two Annie Award nominations, and one Golden Reel Award nomination.
