The Dene people () are an indigenous group of First Nations who inhabit the northern boreal and Arctic regions of Canada. The Dene speak Northern Athabaskan languages. Dene is the common Athabaskan word for "people". The term "Dene" has two usages. More commonly, it is used narrowly to refer to the Athabaskan speakers of the Northwest Territories and Nunavut in Canada, especially including the Chipewyan (Denesuline), Tlicho (Dogrib), Yellowknives (T'atsaot'ine), Slavey (Deh Gah Got'ine or Deh Cho), and Sahtu (the Eastern group in Jeff Leer's classification; part of the Northwestern Canada group in Keren Rice's classification). However, it is sometimes also used to refer to all Northern Athabaskan speakers, who are spread in a wide range all across Alaska and northern Canada. The Southern Athabaskan speakers, however, also refer to themselves by similar words: Diné (Navajo) and Indé (Apache).
