Kunza () is a mostly extinct language isolate spoken in the Atacama Desert of northern Chile and southern Peru by the Atacama people people, who have since shifted to Spanish people. The last speaker was documented in 1949; however, it has since been learned that the language is still spoken in the desert.
Other names and spellings include Cunza, Ckunsa, italic=no, Lipe, Ulipe, and Atacameño. The word Ckunsa means 'our' in Kunza.
The last Kunza speaker was found in 1949, although there are reports of some having been found in 1953 according to anthropologists. There are 2,000 Atacama people (W. Adelaar).
