Guajira Peninsula (Spanish: Peninsula de La Guajira, also spelled Goajira, mainly in colonial period texts), is a peninsula in northern Colombia and northwestern Venezuela in the Caribbean. It is the northernmost peninsula in South America and has an area of 25,000 km² (9,700 sq mi) extending from the Manaure Bay (Colombia) to the Calabozo Ensenada in the Gulf of Venezuela (Venezuela), and from the Caribbean to the Serranía del Perijá mountains range. It was the subject of a dispute between Venezuela and Colombia in 1891, and on arbitration was awarded to the latter and joined to its Magdalena Department. Nowadays, most of the territory is part of Colombia, making part of La Guajira Department, while the remaining strip pertains to the Venezuelan Zulia State.
