The Treaty of Lima was a boundary treaty signed on June 3, 1929. The agreement put an end to the territorial dispute regarding the provinces of Tacna and Arica, which had been administered by Chile since 1883.
The treaty divided Tacna Province, the first-level administrative division established by Chile, into two parts. Tacna was awarded to Peru, and Chile retained its sovereignty over Arica. Chile also agreed to pay up to US$6 million (about £1.23 million; equivalent to $113 million in 2025) in compensation to Peru. It established the border between both states and granted Peru the administration of the Tacna–Arica railway and a pier in the Port of Arica. The treaty was signed on 3 June 1929 in Lima by then-Peruvian Representative Pedro José Rada y Gamio and Chilean Representative Emiliano Figueroa Larrain.
