Sioux is a Siouan language spoken by over 30,000 Sioux in the United States and Canada, making it the fifth most spoken indigenous language in the United States or Canada, behind Navajo, Cree, Inuit languages and Ojibwe.

The Western Siouan languages can be divided into Missouri River languages (such as Crow and Hidatsa), Mandan, Mississippi River languages (such as Dakotan, Chiwere-Winnebago, and Dhegihan languages), and Ohio Valley Siouan branches.

See Lakota sound system and Dakota sound system.

Though generally taught and considered by speakers as a separate language, Lakota is mutually intelligible with the other two languages (such as Dakota language), and is considered by most linguists as one of the three major varieties of the Sioux language.

Closely related to the Sioux language are the Assiniboine and Stoney languages, whose speakers use the self-designation term (autonym) Nakhóta or Nakhóda.

Along with the closely related Stoney, Assiniboine is an n variety of the Dakotan languages, meaning its autonym is pronounced with an initial n (thus: Nakʰóta as opposed to Dakʰóta or Lakʰóta, and Nakʰóda or Nakʰóna as opposed to Dakʰód or Lakʰól).
