Jellystone! is an American animated comedy television series developed by C. H. Greenblatt for the streaming service HBO Max. The series is produced by Warner Bros. Animation and features reimagined versions of various characters by Hanna-Barbera. It premiered on July 29, 2021.
Jellystone! is the first series to feature many of Hanna-Barbera's trademark characters (such as Yogi Bear and Huckleberry Hound) since 1991's Yo Yogi!, 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.
The first season consisted of 21 episodes, with most episodes combined in pairs, but was produced as separate 11-minute episodes, including the Halloween episode "Spell Book". The second season was released on March 17, 2022. On March 2, 2022, it was announced that it was renewed for an additional 40 episodes though it was eventually cut down to 37 episodes. There is also a 22-minute special that features Cartoon Network characters called "Crisis on Infinite Mirths" and it also serves as the season 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.
