The Mumuye–Yendang languages are a proposed group of Savanna languages spoken in eastern Nigeria.
They were labeled "G5" in Joseph Greenberg's Adamawa language-family proposal.
Their unity is not accepted by Güldemann (2018).
[1] Only Mumuye and Yendang proper have more than about 5,000 speakers.
Mumuye is the most widely spoken Adamawa language.
