Pisco Elqui is a Chilean village (pueblo) in the commune of Paihuano, Elqui Province, Coquimbo Region. It is located in the Elqui Valley, 107 km east from La Serena, at about 1,300 metres above sea level.
This was the area where pisco was distilled in the early history of Chile. The original name of the town was La Greda. It was later changed to La Unión. In February 1936, the Law Decree 5,798 changed its name to Pisco Elqui to reinforce Chile's claim to have rights over the alcoholic drink, pisco.
