# Lower Cross River languages

The Lower Cross River languages form a branch of the Cross River languages of Cross River State, Nigeria. They consist of the divergent Obolo language (or Andoni, 200,000 speakers), and the core of the branch, which includes the 4 million speakers of the Efik-Ibibio cluster.
* Obolo
* Lower Cross proper: Efik-Ibibio, Ibino (Ibeno), Oro (Oron), Okobo, Iko, Ebughu, Ilue, Enwang-Uda, Usaghade
Additionally, Ethnologue lists several more languages within the Efik-Ibibio cluster. (See Ibibio-Efik languages.)
Forde and Jones (1950) considered Ibino and Oro to be Efik-Ibibio.
