* Indigenous languages: Montana is home to a number of Indigenous tribes, each with their own distinct language. These include:
* Blackfeet: Spoken by the Blackfeet Nation in the northwest of the state.
* Salish: Spoken by the Confederated Salish and Kootenai Tribes in the west.
* Crow: Spoken by the Crow Nation in the south-central part of the state.
* Assiniboine: Spoken by the Fort Peck Assiniboine and Sioux Tribes in the northeast.
* Cheyenne: Spoken by the Northern Cheyenne Tribe in the southeast.
* Arikara: Spoken by the Fort Berthold Tribes in the north-central part of the state.
* Mandan: Spoken by the Mandan, Hidatsa, and Arikara Nation in the north-central part of the state.

* Dakota: Spoken by the Sisseton-Wahpeton Oyate in the eastern part of the state.
* Cree: Spoken by the Rocky Boy's Indian Reservation in the north-central part of the state.
* Other Indigenous languages: Several smaller Indigenous languages are also spoken in Montana, including Kiowa, Arapaho, and Ojibwe.
* Spanish: Due to historical and recent migration patterns, Spanish is spoken by a growing number of Montanans, particularly in urban areas.
* German: Montana has a long history of German immigration, and German is still spoken by some residents, particularly in rural areas.
* Other European languages: Other European languages spoken in Montana include French, Italian, Polish, and Norwegian, though their prevalence has declined over time.
It's important to note that the prevalence of these languages varies widely across the state, with certain languages being more common in specific regions or communities.
The exact number of speakers for each language is difficult to determine, as the US Census does not collect detailed data on languages spoken other than English. However, it's clear that Montana is a state with a rich linguistic diversity.
