Regular Show season 8

The eighth and final season of the American animated comedy television series Regular Show (promoted as Regular Show in Space), created by J. G. Quintel, originally aired on Cartoon Network in the United States. Quintel created the series' pilot using characters from his comedy shorts for the canceled anthology series The Cartoonstitute. He developed Regular Show from his own experiences in college. Simultaneously, several of the show's main characters originated from his animated shorts The Naïve Man from Lolliland and 2 in the AM PM. The series was renewed for an eighth and final season on July 7, 2015. The season ran from September 26, 2016 to January 16, 2017 and was produced by Cartoon Network Studios.

Taking place shortly after the seventh season finale, Mordecai and Rigby along with rest of the park itself eventually wind themselves in space, where they must learn to adapt to their newfound surroundings all while getting into the same comedic antics as with the previous seasons. The season later progresses to being narrative-driven once the crew ends up confronting Pops’s brother Anti-Pops, a cataclysmic being, forcing them to uncover the truth behind Pops’s past.

The series finale included a reference to Quintel's original short “The Naive Man from Lolliland,” in which Pops's original design is created. The episodes "Can You Ear Me Now?" and "The Ice Tape" feature the final voice performances of both John Cygan, who died on May 13, 2017 and David Ogden Stiers, who died on March 3, 2018.

Calvin Wong served as supervising director for the season. The story writers for the season are Quintel, Sean Szeles, Gina Ippolito, Patrick Baker, and Matt Price, who is also the story editor, while being produced by Cartoon Network Studios.
