Missouri_†

The Missouria or Missouri (in their own language, Niúachi, also spelled Niutachi) are a Native American tribe that originated in the Great Lakes region of United States before European contact. The tribe belongs to the Chiwere division of the Siouan language family, together with the Iowa and Otoe.
Historically, the tribe lived in bands near the mouth of the Grand River at its confluence with the Missouri River; the mouth of the Missouri at its confluence with the Mississippi River, and in present-day Saline County, Missouri. Since removal, today they live primarily in Oklahoma.
