Kiowa or Cáuigú IPA: [kɔ́j-gʷú]) people are a Native American tribe and an Indigenous people of the Great Plains of the United States. They migrated southward from western Montana into the Rocky Mountains in Colorado in the 17th and 18th centuries, and eventually into the Southern Plains by the early 19th century. In 1867, the Kiowa were moved to a reservation in southwestern Oklahoma.

Plains Indians or Indigenous peoples of the Great Plains and Canadian Prairies are the Native American tribes and First Nation band governments who have historically lived on the Interior Plains of North America. While hunting-farming cultures have lived on the Great Plains for centuries prior to European contact, the region is known for the horse cultures that flourished from the 17th century through the late 19th century. Their historic nomadism and armed resistance to domination by the government and military forces of Canada and the United States have made the Plains Indian culture groups an archetype in literature and art for Native Americans everywhere.
