Jellystone! is an American animated comedy television series developed by C. H. Greenblatt for the streaming service HBO Max. Produced by Warner Bros. Animation, the show features and centers around oddly reimagined versions of various characters by Hanna-Barbera, who live together in the fictional town of Jellystone. The show premiered on July 29, 2021, and ended on March 6, 2025, after three seasons consisting of 77 episodes.

Having been a fan of Hanna-Barbera content, Greenblatt began developing on Jellystone! according to him in January 2020, with Unikitty! director Careen Ingle and former Harvey Beaks writer and storyboard artist Hannah Ayoubi. During production, he and his crew decided to have every single character exist in a single town together, changing some of their core traits to make them more likeable while adapting to modern audiences, instead of recreating their past adventures. The show is the first series to feature many of Hanna-Barbera's trademark characters (such as Yogi Bear and Huckleberry Hound) since Yo Yogi! (1991), as well as the first production since the closure of the Hanna-Barbera studios, and also the first television series featuring them without the respective studios' founders, William Hanna and Joseph Barbera, who died in 2001 and 2006, respectively.

Each episode is 11 minutes long, aside from season 3 containing three 22-minute specials. The first season consisted of 21 episodes, with most episodes combined in pairs, though was produced as separate 11-minute episodes, including the Halloween episode "Spell Book" which was released on its own. The second season was released on March 17, 2022 with 19 episodes. On March 2, 2022, it was announced that it was renewed for a third season of 40 episodes, though it was eventually cut down to 37 episodes to make room for the 22-minute specials. There is also a 22-minute special that features Cartoon Network characters called "Crisis on Infinite Mirths" and it also serves as the series finale in the production order. The first half of season three was released on Max on February 22, 2024. The second half of season 3 was released on March 6, 2025.
