The Alabama or Alibamu are a Southeastern culture people of Native Americans, originally from Alabama. They were members of the Muscogee Creek Confederacy, a loose trade and military organization of autonomous towns; their home lands were on the upper Alabama River.

Alabama, also known as Alibamu, is a Native American language, spoken by the Alabama-Coushatta tribe of Texas. It was once spoken by the Alabama-Quassarte Tribal Town of Oklahoma, but there are no more Alabama speakers in Oklahoma. It is a Muskogean language, and is believed to have been related to the Muklasa and Tuskegee languages, which are no longer extant. Alabama is closely related to Koasati and Apalachee, and more distantly to other Muskogean languages like Hitchiti, Chickasaw and Choctaw.
