Bonaire ( /bɒˈnɛər/; Dutch: Bonaire, Papiamentu: Boneiru) is a special municipality (officially public body) of the Netherlands, consisting of the Caribbean 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. The name Bonaire is thought to have originally come from the Caiquetio word 'Bonay'. The early Spanish and Dutch modified its spelling to Bojnaj and also Bonaire, which means "Good Air".

Bonaire was part of the Netherlands Antilles until the country's dissolution on 10 October 2010, when the island (including Klein Bonaire) became a special municipality within the country of the Netherlands.

Bonaire's earliest known inhabitants were the Caquetio Indians, a branch of the Arawak who came by canoe from Venezuela in about AD 1000. Archeological remains of Caquetio culture have been found at certain sites northeast of Kralendijk and near Lac Bay. Caquetio rock paintings and petroglyphs have been preserved in caves at Spelonk, Onima, Ceru Pungi, and Ceru Crita-Cabai. The Caquetios were apparently a very tall people, for the Spanish name for the ABC Islands was 'las Islas de los Gigantes' or 'the islands of the giants.'
