Black Pearl Island is the setting of the Black Pearl Boss Battle, which is the conclusion of The Black Pearl Crew Story Quest. The island's sole purpose is for the Royal Navy to house The Black Pearl after confiscating it from Jack Sparrow. The island is located in the outskirts of the Caribbean and can only be accessed through the Treasure Map section of the Lookout Tab of a pirate's Sea Chest.

The island is heavily guarded by Navy Panthers, Seaside Forts, and the massive Goliath.
