The Ambassador Extraordinary and Plenipotentiary of Chile in Peru is the official representative of the Government in Santiago de Chile to the Government of Peru.

Both countries established relations in 1822[2] and maintained them in an amicable manner until the War of the Pacific in 1879, which has left a feeling of Anti-Chilean sentiment in Peru since.

[3] This situation improved somewhat however after the signing of the 1929 Treaty of Lima, although a minor territorial dispute between both states remains to this day.

Relations between both countries were first severed during the aforementioned War of the Pacific, being reestablished in its immediate aftermath.

During the Chilean–Peruvian territorial dispute over the Chilean-controlled territories of Tacna and Arica, Peru twice severed relations with Chile: first in 1901 until 1906 over the Chilenization policies carried out by Chile over the territories, and then in 1910 until 1928 after the expulsion of Peruvian priests from the city of Tacna.
