The Chakchiuma were a Native American tribe of the upper Yazoo River region of what is today the state of Mississippi.
In the late 17th century, French explorers identified the Chakchiuma as "a Chicacha nation," indicating that they were related to the Chickasaw and similar Western Muskogean speaking–tribes. They likely shared a common origin as the Chickasaw and Choctaw people and merged into the Chickasaw Nation in the mid-18th century.
