Innu-aimun or Montagnais is an Algonquian language spoken by over 10,000 Innu in Labrador and Quebec in Eastern Canada. It is a member of the Cree–Montagnais–Naskapi dialect continuum and is spoken in various dialects depending on the community.

The Innu / Ilnu or Innut / Innuat / Ilnuatsh ("people"), formerly called Montagnais from the French colonial period, are the Indigenous inhabitants of territory in the northeastern portion of the present-day province of Labrador and some portions of Quebec. They refer to their traditional homeland as Nitassinan or Innu-assi.
