The Brulé are one of the seven branches or bands of the Teton (Titonwan) Lakota American Indian people. They are known as Sičhą́ǧu Oyáte —Sicangu Oyate—, Sicangu Lakota, or "Burnt Thighs Nation". Learning the meaning of their name, the French called them the Brûlé. The name may have derived from an incident where they were fleeing through a grass fire on the plains.

The Lakota are a Native American people. Also known as the Teton Sioux, they are one of the three prominent subcultures of the Sioux people, with the Eastern Dakota (Santee) and Western Dakota (Wičhíyena). Their current lands are in North and South Dakota. They speak Lakȟótiyapi—the Lakota language, the westernmost of three closely related languages that belong to the Siouan language family.
