Plenty Coups (Crow: Alaxchíia Ahú, "many achievements"; 1848 – 1932) was the principal chief of the Mountain Crows (the Apsáalooke) of the Crow Nation and a visionary leader. He allied the Crow with the whites when the war for the West was being fought, because the Sioux and Cheyenne (who opposed white settlement of the area) were the traditional enemies of the Crow.
