The Spirit World (also known as the Spirit Tree) is the home realm of Zuzo and all the other spirits in the Disney Channel animated series Elena of Avalor. The entire Spirit World is one big colorful tree, where each branch represents all different types of spirits.
- Good Spirit Branch: Home to some of the good spirits.
- Bad Spirit Branch: As the name implies, home to all the bad spirits in the Spirit World, including Orizaba.
- Ancestors Branch: Home to the spirits of everyone's ancestors.
- Spirit Guide Branch: Home to all the animal spirit guides, including Zuzo and Cacahuate. On this branch they have their own school where they teach new animal spirits to become spirit guides.
- Loop Branch: Homed to the Zanies, who are known to be free spirited.
- The idea for the spirit world was inspired by Mexican Tree of Life folk art.
