The Diaguita , also called Diaguita-Calchaquí, are a group of South American indigenous peoples. The Diaguita culture developed between the 8th and 16th centuries in what are now the provinces of Salta, Catamarca, La Rioja and Tucumán in northwestern Argentina, and in the Atacama and Coquimbo regions of northern Chile.
The Diaguita were one of the most advanced Pre-Columbian cultures in Argentina. They had sophisticated architectural and agricultural techniques, including irrigation, and are known for their ceramic art.
