The Omotic languages are a traditionally recognized but disputed grouping of languages spoken mainly in southwestern Ethiopia, around the Omo River region, and in parts of southeastern Sudan (Blue Nile State). This classification conventionally includes the Damotic (North Omotic), Mao, Dizoid, and Aroid (South Omotic) languages.

Some of these languages are written in the Geʽez script, while others use the Latin alphabet. They are generally agglutinative and exhibit complex tonal systems, as in the Bench language. The group comprises about 7.9 million speakers.

They are generally classified within the Afroasiatic family, though their inclusion in it, as well as the validity of Omotic as a coherent language group, are questioned by some linguists.

The North and South Omotic branches ("Nomotic" and "Somotic") are universally recognized, with some dispute as to the composition of North Omotic. The primary debate is over the placement of the Mao languages. Bender (2000) classifies Omotic languages as follows:

Apart from terminology, this differs from Fleming (1976) in including the Mao languages, whose affiliation had originally been controversial, and in abolishing the "Gimojan" group.^{[clarification needed]} There are also differences in the subclassification of Ometo, which is not covered here.

Hayward (2003) separates out the Mao languages as a third branch of Omotic and breaks up Ometo–Gimira:

Blench (2006) gives a more agnostic classification:

Bosha† is unclassified; Ethnologue lists it as a dialect of Kafa but notes it may be a distinct language.
