The Hidatsa (called Minnetaree by their allies, the Mandan) are a Siouan people, a part of the Three Affiliated Tribes. The Hidatsa name for themselves is Nuxbaaga ("Original People"). The name Hidatsa, said to mean "Willows," was formerly borne by one of the tribal villages. When the villages consolidated, the name was adopted for the tribe as a whole. Their language is related to that of the Crow, and they are often considered a parent tribe to the modern Crow in Montana. Occasionally they have also been confused with the Gros Ventres in Montana.
