The Islan Territory of Bonaire (Dutch: Eilandgebied Bonaire, Papiamento: Teritorio Insular di Boneiru) is one of five island areas (Eilandgebieden) of the Netherlands Antilles, consisting of the main island of Bonaire and, nestled in its western crescent, the uninhabited islet of Klein Bonaire. Together with Aruba and Curaçao it forms a group referred to as the ABC islands of the Leeward Antilles, the southern island chain of the Lesser Antilles.
