Upper Peru (Spanish: Alto Perú) was the region in the Viceroyalty of Peru, and after 1776, the Viceroyalty of the Río de la Plata, comprising the governorships of Potosí, La Paz, Cochabamba, Los Chiquitos, Moxos and Charcas (since renamed Sucre). It was governed by the Audiencia of Charcas.
Following the Bolivian War of Independence, the region became an independent country and was renamed Bolivia in honour of Simón Bolívar.
