The Crow Language Family is a group of languages spoken by the Native American Crow tribe. It is part of the SIOUAN language family, which is a large language family that includes many languages spoken in the Great Plains and Midwest regions of the United States. The Crow Language Family is made up of several dialects, including Crow, Hidatsa, and Dakota. The Crow language is still spoken today, although it is considered endangered due to the small number of speakers.
