Chamba Leko is one of two languages spoken by the Chamba people, the other being Chamba Daka. It is a member of the Leko branch of Savanna languages, and is spoken across the northern Nigerian–Cameroonian border.

Chamba is also spelled 'Samba', Leko also 'Leeko', 'Lego' or 'Lekon'. The language is also known as Suntai.

Samba, also called Samba Leeko, is highly distinct from Chamba Daka, also called Daga Mumi ('language of the Daka'), spoken in Nigeria by another subgroup of the Chamba people. These two languages are respectively classified in groups 2 and 3 of the Adamawa branch by Joseph Greenberg (see Adamawa languages).^[2]

• Daganjonga, spoken in two enclaves of 25,000 speakers surrounded by Grassfields languages, near the Ndop Plain (more than 400 kilometers from the Alantika Mountains). It is spoken in the villages of Balikumbat, Baligashu, Baligashu (Balikumbat commune, Ngoketunjia department, North-West Region) and Baligam (Santa commune, Mezam department, North-West Region)
