Jurassic World: Chaos Theory is an American science fiction action-adventure animated television series developed by Scott Kreamer and Zack Stentz for Netflix and is the second television series in the Jurassic Park franchise. It serves as a direct sequel to Jurassic World Camp Cretaceous (2020–2022), and takes place both before and during the events of Jurassic World Dominion (2022). Aaron Hammersley and Kreamer serve as showrunners and executive produce the series along with Steven Spielberg, Colin Trevorrow, and Frank Marshall. It features Paul-Mikél Williams, Sean Giambrone, Kausar Mohammed, and Raini Rodriguez reprising their voice roles from Camp Cretaceous, with Darren Barnet and Kiersten Kelly joining the main cast.

The first season premiered on May 24, 2024, followed by a second season on October 17, 2024, and a third season on April 3, 2025. The fourth and final season premiered on November 20, 2025.

Six years after the events of Jurassic World Camp Cretaceous, "the Nublar Six" reunite and embark on an adventure to unravel a global conspiracy that threatens dinosaurs and humankind alike while learning the truth about what happened to one of their own.

Several notable creatures from Jurassic Park media make an appearance. This includes the blind-eyed Allosaurus from Battle at Big Rock who is responsible for Brooklynn's suspected death while the quartet of trained Atrociraptors Ghost, Panthera, Tiger, and Red as well as the Giganotosaurus and Therizinosaurus, are all from Jurassic World Dominion. It also includes Bumpy, Ben's Ankylosaurus companion with an asymmetrical face, and Big Eatie, a mother Tyrannosaurus rex from Mantah Corp Island, who were both introduced in Camp Cretaceous. Boss, a Carnotaurus from Jurassic World: Fallen Kingdom, the Tyrannosaurus rex Rexy from Jurassic Park, and both Buck and Doe from The Lost World: Jurassic Park, also make an appearance.

Other notable dinosaurs that appear include: Blonde and Brunette, a pair of Becklespinaxes transported by Jensen and Jared; Prue, Piper, and Phoebe, a Stygimoloch trio serving as a roadside attraction for Bobby Nublar; Major, a Majungasaurus held captive on Captain Lang's cargo ship; Geba, a playful Gallimimus who lives on the Mballo family farm; Gordon, a one-footed Compsognathus under Ronnie's care; a blind leucistic Baryonyx created by Dr. Sarr; a Pyroraptor escapee from Biosyn Valley; Smoothie, a baby Ankylosaurus under Kenji's protection who hatched from Bumpy's egg; Allan, Barbara, Kenneth, and Kristy, a pack of Dilophosaurus living in Biosyn Valley, and Blender, Bumpy's mate and Smoothie's father.

As Jurassic World Camp Cretaceous finished production, executives at DreamWorks Animation Television and Netflix were interested in developing a follow-up. While Camp Cretaceous showrunner Scott Kreamer initially turned down the offer, he decided to work on a second series after he and co-showrunner Aaron Hammersley were given "an early rundown" of the film Jurassic World Dominion (2022), which inspired him to create a direct sequel starring older versions of the Camp Cretaceous cast in the vein of the later Harry Potter films. After deciding to work on the series, they reunited with story editor Bethany Armstrong Johnson to conceive the story for the series.

In November 2023, at Netflix's Geeked Week virtual event, the follow-up series titled Jurassic World: Chaos Theory was announced. In June 2024, Netflix announced a second season of the series. In January 2025, Netflix announced a third season of the series. In June 2025, Netflix announced a fourth and final season of the series.

The series is set shortly before the events of Jurassic World Dominion. Kreamer was intrigued by the world depicted in the film, in which dinosaurs have established themselves on the mainland, and wanted to explore "what does that look like for an everyday person?" The producers also wanted to emphasize the characters now being older and "at that uncertain age where one is trying to figure out who they are and where they fit in the world," while facing their trauma, the proliferation of dinosaurs on the mainland, and a recent loss. The writers also made the show a conspiracy thriller in contrast to the more adventurous tone of Camp Cretaceous.
