List of episodes/Season 10

Adventure Time was confirmed for another season (known as "Season 9" by the time) by Kent Osborne on July 21, 2016, and it's the final season of the show. According to Adam Muto, the number of episodes ordered by the network as part of the season was substantially lower than it had been, leading the production crew to believe that the series is either ending or going to end soon.

Storyline writing for the season ended in mid-November 2016 and the last storyline meeting was held on November 21. Osborne tweeted that the show's final script was pitched to storyboarders on November 28; the episode was pitched to the show's producers during the third week of December 2016. A number of voice actors, including Maria Bamford and Andy Milonakis, confirmed that voice recording for the season (and series) ended on January 31, 2017. Regular production of the series ended on November 16, 2017.
