'Adventure Time' has one of the deepest rosters of characters for any TV show not named 'The Simpsons.' What helps make all these characters so special and memorable, are the talented voice actors who contribute to the show. A mix of trained voiceover artists and actors, singers and comedians, the show has created an animated world unlike any other.

Because we get asked often, we decided to put together a definitive guide to the 'Adventure Time' voice cast that helps make the show so incredible. There will be some faces you don't recognize, but also get ready to go, "Hey, I didn't know that's who that was!"
