The best animated sci-fi and fantasy shows are more than just “cartoons.” Animated television shows have a unique ability to create truly fantastical and out-of-this-world fantasy and science fiction worlds. No fancy sets, special effects or costumes - if it can be drawn it can be done! If you’ve been looking for the sci-fi and fantasy stories that'll ignite your imagination while also enjoying the visuals of a cartoon, this list of the best animated fantasy and science fiction series of all time will help you figure out what needs to go into your queue.

Having a talking animal friend or a robot in a cartoon doesn't necessarily make for a great animated science fiction and fantasy show. The fantasy and sci-fi elements need to be a consistent and large part of the story. Some of the best sci-fi cartoons tell the same stories a live-action show would, they just happen to be animated, such as Futurama or the animated Star Wars series. The best fantasy cartoons get to have a lot of fun with the animation and shows such as Gravity Falls and OK K.O.! Let's Be Heroes embrace the flexibility of their medium.
