The Westo were a Native American tribe encountered in the Southeast by Europeans in the 17th century. They probably spoke an Iroquoian language. The Spanish called these people Chichimeco (not to be confused with Chichimeca in Mexico), and Virginia colonists may have called the same people Richahecrian. Their first appearance in the historical record is as a powerful tribe in colonial Virginia, who had migrated from the mountains into the region around present-day Richmond.
