Le lac Agassiz était un immense lac proglaciaire occupant entre le Xe millénaire et le VIIe millénaire av. J.-C. la partie centrale du continent nord-américain. Postulée par William Keating en 1823, son origine glaciaire fut démontrée en 1879 par Warren Upham qui lui donna le nom du scientifique américano-suisse Louis Agassiz.
