Copper Island is one of the islands of the Southern Arc Islands. It lies is the southern half of the archipelago, though close to the "middle". It is one of the Metal Islands, the northernmost island of that group. Unlike the other Metal Islands, there are no mines at all on the island, and there is no known copper on the island (the other islands do/did have the metal of their name on them). Instead, the island is named for the brown cliffs that grace large amounts of its shores. The largest settlement on the island is Coppercliff.
The island belongs to the Copper Island District.
