Sonic's island is a location that appears in the Sonic the Hedgehog film series produced by Paramount Pictures. It is a tropical island on another planet where Sonic the Hedgehog grew up under Longclaw's care.
Sonic's Island is a lonely spot of land in the middle of a vast ocean. Described as a paradise, the island supposedly had everything according to Sonic. Its landscape consists of brown-checkered cliffs, grassy hills, open fields, sandy beaches, cascading waterfalls, and abstract cliff formations, such as loop-de-loops. There are also various types of flowers resembling sunflowers, palm trees, regular trees, bushes, and smaller forms of vegetation.
The island has very few known artificial constructs on it, featuring only a few wooden hanging bridges and a couple of small wooden huts in the tree tops that served as Longclaw and Sonic's place of residence.
One day, after Sonic returned home from a run around the island to bring a flower to Longclaw, the pair were attacked by a tribe of echidnas, led by Pachacamac, who had followed Sonic there to claim the hedgehog's power. During the attack, Longclaw was injured by an arrow while trying to escape with Sonic, leaving her with no choice but to open a portal to Earth with a Ring and sent Sonic through it with her remaining Rings in order to keep Sonic safe. Longclaw herself, however, remained behind on the island in order to keep the echidna tribe at bay while the Ring portal closed.

Originally, Sonic lived on this island paradise with his sensei, Longclaw. One day however, power-hungry bad guys came to Sonic and Longclaw's island, seeking Sonic's power. Ultimately, Longclaw gave her life to help Sonic escape to a distant planet across the universe called Earth, where he could remain in hiding.
- Sonic's island is based on the tale of Christmas Island from the Sonic the Hedgehog Technical Files, but its appearance is based on South Island.
