Yahgan language

Yahgan or Yagán (also spelled Yaghan, Jagan, Iakan, and also known as Yámana, Háusi Kúta, or Yágankuta), is an extinct language that is one of the indigenous languages of Tierra del Fuego, spoken by the Yahgan people. It is regarded as a language isolate, although some linguists have attempted to relate it to Kawésqar and Chono.

Yahgan was also spoken briefly on Keppel Island in the Falkland Islands at a missionary settlement. In 2017, Chile's National Corporation of Indigenous Development convened a workshop to plan an educational curriculum in the Yahgan language, and in June 2019 it planned to inaugurate a language nest in the community of Bahía Mejillones, near Puerto Williams. The government also funded the publication of a "concise and illustrated dictionary" of the Yahgan language.

Following the death of Cristina Calderón (1928–2022) of Villa Ukika on Navarino Island, Chile, no native speakers of Yahgan remain.
