Catavi is a tin mine in Bolivia, near the city of Llallagua in the province of Bustillos, Potosí Department.
Apart from the Catavi-Siglo XX mining complex; it refers as well to a residential area, to a mill processing ore and to an administrative office of the Corporación Minera de Bolivia (COMIBOL).
Catavi and other mines were placed under the control of a new state agency, the Corporación Minera de Bolivia (COMIBOL).
On June 24, 1967, government troops under the orders of General René Barrientos and a new military junta marched on the mine and committed the largest massacre of workers in Bolivian history.
In 1987, as part of an economic restructuring deal with the IMF and World Bank, the government shut down production at Catavi.
