The Kawésqar, also known as the Kaweskar, Alacaluf, Alacalufe or Halakwulup, are an Indigenous people who live in Chilean Patagonia, specifically in the Brunswick Peninsula, and Wellington, Santa Inés, and Desolación islands northwest of the Strait of Magellan and south of the Gulf of Penas. Their traditional language is known as Kawésqar; it is endangered as few native speakers survive.
It has been proposed that the Caucahue people known from colonial-era records either are ancient Kawésqar or came to merge with the Kawésqar.
