The nationalization of all large copper mines in Chile is completed.

The nationalization of the Chilean copper industry, commonly described as the Chilenization of copper was the process by which the Chilean government acquired control of the major foreign-owned section of the Chilean copper mining industry. It involved the three large world-class mines known as 'La Gran Mineria' and three smaller operations. The Chilean-owned smaller copper mines were not affected. The process started under the government of President Carlos Ibáñez del Campo (1952–1958), and culminated during the government of President Salvador Allende (1970–1973), who completed the nationalization. This "act of sovereignty" was the espoused basis for a later international economic boycott, which further isolated Chile from the world economy, worsening the state of political polarization that led to the 1973 Chilean coup d'état.

Chile is the world's largest producer of copper and has been so uninterruptedly since 1983. This activity provides a substantial part of the Chilean state's revenue: slightly less than 6% in 2020, with state-owned copper company Codelco alone generating 2.6% of state revenue.
