The Dakelh (ᑕᗸᒡ) or Carrier language is a Northern Athabaskan language. It is named after the Dakelh people, a First Nations people of the Central Interior of British Columbia, Canada, for whom Carrier has been a common English name derived from French explorers naming of the people. Dakelh people speak two related languages. One, Babine-Witsuwit'en is sometimes referred to as Northern Carrier.
