This is a list of indigenous languages that are or were spoken in the present territory of Argentina.
Tentative classification A large number of languages once spoken in Argentina have disappeared.
In some cases, the languages disappeared along with the ethnic groups that spoke them; in other, the acculturation and transculturation phenomena associated with deep changes in the living conditions of the indigenous peoples caused the extinction, even if a number of individuals of the ethnical group still survive.
Other extinct languages are known just by the ethnic group that spoke them, since very scarce (if any) linguistic material remains.
Among them: Omaguaca; Sanavirón; several languages probably belonging to the Guaycurú family but known by their Guaraní ethnonyms as Mbayá, Payaguá, Minuané, Mbeguá, Timbú, Corondá, Quiloazá and Colastiné; and others related to the Chon stock, as Manek'enk and Teushen.
