The Chickasaw language is a Native American language of the Muskogean family. It is agglutinative and follows the word order pattern of subject–object–verb (SOV). The language is closely related to, though perhaps not entirely mutually intelligible with, Choctaw. It is spoken by the Chickasaw tribe, now residing in Southeast Oklahoma, centered on Ada.

The Chickasaw are an Indigenous people of the Southeastern Woodlands, United States. Their traditional territory was in northern Mississippi, northwestern and northern Alabama, western Tennessee and southwestern Kentucky. Their language is classified as a member of the Muskogean language family. In the present day, they are organized as the federally recognized Chickasaw Nation.
