Kawésqar (Qawasqar), also known as Alacaluf,[3] is a critically endangered Alacalufan language spoken in southern Chile by the Kawésqar people.

Originally part of a small family,[4] only the northern language remains.

In 2009, only a handful of elderly people spoke the language, most of whom lived on Wellington Island off the southwest coast of Chile.
