Atacama Province (Spanish: Provincia de Atacama), also known as the Litoral Province of Atacama (Spanish: Provincia Litoral de Atacama), was a province of Bolivia that existed from 1829 to 1839, with its capital in the port of La Mar, named after José de la Mar, who fought at the battle of Ayacucho.

[1][2] Starting in 1836, as part of the Bolivian State, it was under special administration of the Peru–Bolivian Confederation, since access to this territory was easier through a Peruvian port than by land through Bolivian territory.

[3] On July 1, 1829, Bolivian President Andrés de Santa Cruz, by decree, created this new subnational entity, elevating the rank of the province of Atacama—until then a province of Potosí Department—into an independent province with a governor which responded directly to the president, thus reaching a hierarchy higher than a common province, but lower than a department, also having a senator as a representative before the Senate of Bolivia.
