Dragon Island is a privately owned island off the northeast coast of New Zealand's Great Barrier Island. It is located 95 kilometres to the northeast of Auckland.
The island provides Harataonga Bay on Great Barrier Island with shelter from easterly and southeasterly winds by blocking the bay from the Pacific storms. The island is itself in relatively calm water, sheltered by the larger Rakitu Island to the north.
Once farmed, the island has now reverted to scrub.
