The Choctaw Nation of Oklahoma (Choctaw: Chahta Okla) is a federally recognized Native American tribal nation with an Indian reservation encompassing portions of Southeastern Oklahoma in the United States.
The Choctaw Nation of Oklahoma (CNO) is one of three federally recognized tribes of Choctaw people, an Indigenous people of the Southeastern Woodlands. The other two are the Mississippi Band of Choctaw Indians and Jena Band of Choctaw Indians in Louisiana. The U.S. federal government forcibly removed the Choctaw Nation of Oklahoma from their Mississippi homelands in 1831 to 1833 to Indian Territory, later to become Oklahoma. A smaller group of Mississippi Choctaw were coerced to migrating to Oklahoma in 1908.
