Disappointment Island is one of seven uninhabited islands in the Auckland Islands archipelago, in New Zealand. It is 475 kilometres south of the country's main South Island and 8 kilometres from the northwest end of Auckland Island. It is home to a large colony of white-capped albatrosses: about 65,000 pairs – nearly the entire world's population – nest there. Also on the island is the Auckland rail, endemic to the archipelago; once thought to be extinct, it was rediscovered in 1966.
