The third season of Adventure Time, an American animated television series created by Pendleton Ward, premiered on Cartoon Network on July 11, 2011, and concluded on February 13, 2012, and was produced by Frederator Studios and Cartoon Network Studios. The season follows the adventures of Finn, a human boy, and his best friend and adoptive brother Jake, a dog with magical powers to change shape and size at will. Finn and Jake live in the post-apocalyptic Land of Ooo, where they interact with the other main characters of the show: Princess Bubblegum, The Ice King, Marceline the Vampire Queen, Lumpy Space Princess, and BMO.
This season saw the series grow and progress, featuring the first of the popular Fionna and Cake episodes, as well as marking the first time that fan-submitted content was canonized. Ward also noted that the storyboard artists affected the overall tone of the show, moving it towards more bizarre and spiritual matters. The season was storyboarded and written by Ako Castuera, Tom Herpich, Adam Muto, Rebecca Sugar, Jesse Moynihan, Bert Youn, Kent Osborne, Somvilay Xayaphone, Pendleton Ward, and Natasha Allegri.
The first episode of the season, "Conquest of Cuteness" was watched by 2.686 million viewers; this marked an increase in viewers watching Cartoon Network when compared to the previous season's debut. The season ended with the cliffhanger "Incendium", which was resolved at the start of season four. The season was met with largely positive critical reception. In addition, several episodes and writers were nominated for awards; the episode "Thank You" was nominated for an Annie Award as well as an award at the Sundance Film Festival. "Too Young" was nominated for an Emmy Award. Storyboard artist Rebecca Sugar was also nominated for an Annie Award. Several compilation DVDs that contained episodes from the season were released after the season finished airing. The full season set was released on February 25, 2014, on DVD and Blu-ray.
