The eighth season of Adventure Time, an American animated television series created by Pendleton Ward, premiered on Cartoon Network on March 26, 2016, and concluded on February 2, 2017, and was produced by Frederator Studios and Cartoon Network Studios. It 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, BMO, and Flame Princess.
Tom Herpich, Steve Wolfhard, Jesse Moynihan, Laura Knetzger, Kris Mukai, Lyle Partridge, Graham Falk, Charmaine Verhagen, Sam Alden, Pendleton Ward, Seo Kim, Somvilay Xayaphone, Hanna K. Nyström, Ako Castuera, Aleks Sennwald, Polly Guo, Kent Osborne, and Adam Muto storyboarded and wrote the season. The miniseries Islands, which follows Finn, Jake, BMO (voiced by Niki Yang), and Susan Strong (voiced by Jackie Buscarino) as they leave Ooo and travel across the ocean to solve the mystery of Finn's past, aired during this season. It also features guest animators Alex and Lindsay Small-Butera (who worked on "Beyond the Grotto") and James Baxter (who worked on "Horse and Ball").
The season debuted with the episode "Broke His Crown", which was watched by 1.13 million viewers marking a slight decrease from the previous season finale, "The Thin Yellow Line", which was seen by 1.15 million viewers. "Islands Part 8: The Light Cloud," the eighth-season finale, was watched by 1 million viewers, making it the lowest-rated Adventure Time season finale at the time. Critical reception to the season was mostly positive, with The A.V. Club writer Oliver Sava expressing pleasant bemusement that the show's quality had not suffered despite this season being its eighth. Critics were also complimentary towards the Islands miniseries: In April 2017, Common Sense Media awarded the miniseries "The Common Sense Seal", and at the 69th Primetime Creative Arts Emmy Awards in 2017, the Islands episode "Imaginary Resources" won a Primetime Emmy Award for Outstanding Individual Achievement in Animation. Several compilation DVDs that contain episodes from the season have been released, and a set containing the entire season was released on September 4, 2018.
