The War of the Pacific (Spanish: Guerra del Pacífico), took place from 1879 to 1883, with Bolivia and Peru on one side and Chile on the other. The war ended with a Chilean victory, which gained a significant amount of land from Peru and Bolivia.

Battles were fought in the Pacific Ocean, the Atacama Desert, Peru's deserts, and mountainous regions in the Andes. For the first five months the war played out in a naval campaign, as Chile struggled to establish a sea-based resupply corridor for its forces in the world's driest desert.
