The Arapaho (in French: Arapahos, Gens de Vache) are a tribe of Native Americans historically living on the plains of Colorado and Wyoming. They were close allies of the Cheyenne tribe and loosely aligned with the Lakota and Dakota. The Arapaho language, Heenetiit, is an Algonquian language closely related to Gros Ventre (Ahe/A'ananin), whose people are seen as an early offshoot of the Arapaho. Blackfeet and Cheyenne are the other Algonquian-speakers on the Plains, but their languages are quite different from Arapaho.
