The Atacama border dispute is a dispute between Chile and Bolivia that stems from the transfer of the Bolivian Coast and the southern tip of Peru to Chile in the 19th century through the Treaty of Ancón with Peru and the Treaty of Peace and Friendship of 1904 between Chile and Bolivia after the War of the Pacific (1879–1883). The dispute is considered to be ongoing because Bolivia still claims a sovereign access to the Pacific Ocean. The conflict takes its name from the Atacama Desert on which lies the disputed territory. Due to a transfer of land to both Argentina and Chile during the Chilean annexation of the Bolivian coast in 1879, the Puna de Atacama dispute—this spin-off dispute was settled in 1899.
