Sekani are a First Nations people of the Athabaskan-speaking ethnolinguistic group in the Northern Interior of British Columbia. Their territory includes the Finlay and Parsnip River drainages of the Rocky Mountain Trench. The neighbors of the Sekani are the Babine to the west, Dakelh to the south, Dunneza (Beaver) to the east, and Kaska and Tahltan, to the north, all Athabaskan peoples. In addition, due to the westward spread of the Plains Cree in recent centuries, their neighbors to the east now include Cree communities.
Sekani people call their language [tsek'ene] or [tθek'ene] depending on dialect, which appended with "Dene" (meaning people), means "people on the rocks". "Sekani" is an anglicization of this term. Other forms occasionally found, especially in older sources, are Secunnie, Siccanie, Sikani, and the French Sékanais.
