The Dogon languages are a small closely related language family that is spoken by the Dogon people of Mali and may belong to the proposed Niger–Congo family. There are about 600,000 speakers of its dozen languages. They are tonal languages, and most, like Dogul, have two tones, but some, like Donno So, have three. Their basic word order is subject–object–verb.

The evidence linking Dogon to the Niger–Congo family is mainly a few numerals and some common core vocabulary. Various theories have been proposed, placing them with Gur, Mande, or as an independent branch, the last now being the preferred approach. The Dogon languages show very few remnants of the noun class system characteristic of much of Niger–Congo, leading linguists to conclude that they likely diverged from Niger–Congo very early.^{[citation needed]}

Roger Blench comments,^[1]

Dogon is both lexically and structurally very different from most other [Niger–Congo] families. It lacks the noun-classes usually regarded as typical of Niger–Congo and has a word order (SOV) that resembles Mande and Ịjọ, but not the other branches. The system of verbal inflections, resembling French is quite unlike any surrounding languages. As a consequence, the ancestor of Dogon is likely to have diverged very early, although the present-day languages probably reflect an origin some 3–4000 years ago. Dogon languages are territorially coherent, suggesting that, despite local migration histories, the Dogon have been in this area of Mali from their origin.

Dogon is certainly a well-founded and coherent group. But it has no characteristic Niger–Congo features (noun-classes, verbal extensions, labial-velars) and very few lexical cognates. It could equally well be an independent language family.

The Bamana and Fula languages have exerted significant influence on Dogon, due to their close cultural and geographical ties.

Blench (2015) speculates that Bangime and Dogon languages may have a substratum from a "missing" branch of Nilo-Saharan that had split off relatively early from Proto-Nilo-Saharan, and tentatively calls that branch "Plateau".^[3]

The Dogon consider themselves a single ethnic group, but recognise that their languages are different. In Dogon cosmology, Dogon constitutes six of the twelve languages of the world (the others being Fulfulde, Mooré, Bambara, Bozo and Tamasheq).^[4] Jamsay is thought to be the original Dogon language, but the Dogon "recognise a myriad of tiny distinctions even between parts of villages and sometimes individuals, and strive to preserve these" (Hochstetler 2004:18).

The best-studied Dogon language is the escarpment language Toro So (Tɔrɔ sɔɔ) of Sanga, due to Marcel Griaule's studies there and because Toro So was selected as one of thirteen national languages of Mali. It is mutually intelligible with other escarpment varieties. However, the plains languages—Tene Ka, Tomo Ka, and Jamsay, which are not intelligible with Toro so—have more speakers.

Bangime language (aka Baŋgɛri mɛ), is considered a divergent branch of Dogon by some and a possible language isolate by others (Blench 2005b).
