This is a list of Indigenous languages that are or were spoken in the present territory of Argentina. Although the official language of Argentina is Spanish, several Indigenous languages are in use. Most are spoken only within their respective indigenous communities, some with very few remaining speakers. Others, especially Aymara, Quechua (South Bolivian Quechua and Santiago del Estero Quichua), Toba (Qom) and Guaraní (Western Argentine Guaraní, Paraguayan Guaraní, Mbyá Guaraní), are alive and in common use in specific regions. Finally, some such as Abipón and Yaghan, are now completely extinct. Since 2004 the Guaraní language is official, together with Spanish, in the northeastern Corrientes Province.
