The Muscogee (Creek) Nation is a federally recognized tribe of Muscogee people, also known as the Creek, based in the U.S. state of Oklahoma. Calling themselves Este Mvskokvlke, they are regarded as one of the historical Five Civilized Tribes of the American Southeast. The tribe is descended from the historic Creek Confederacy, a large, heterogeneous group of indigenous peoples of the Southeastern Woodlands.
The Muscogee (Creek) Nation is the largest of the federally recognized Muscogee tribes. The Muskogean-speaking Alabama, Hitchiti, and Natchez people, as well as Algonquian-speaking Shawnee and Yuchi (language isolate) are enrolled in the Muscogee Creek Nation. Historically the latter two groups were from different language families than the Muscogee.
Other federally recognized Muscogee groups include the Alabama-Quassarte Tribal Town, Kialegee Tribal Town, and Thlopthlocco Tribal Town of Oklahoma, the Coushatta Tribe of Louisiana, the Alabama-Coushatta Tribe of Texas, and the Poarch Band of Creeks in Alabama.

Oklahoma Tribal Statistical Area is a statistical entity identified and delineated by federally recognized American Indian tribes in Oklahoma that formerly had a reservation but do not now have a reservation in that state (an exception being the Osage Nation's retention of mineral rights on their reservation). Often, an OTSA will be that of the former Indian Reservation in Oklahoma. They are usually referred to as Tribal Jurisdictional Areas.
