The Andoni people of Rivers and Akwa Ibom States, of Nigeria, are a part of the Ijaw tribe and are also considered as a distinct ethnolinguistic group by others, and a people related to the Annang, Ibibio and Efik people of Akwa Ibom State and Cross River State in Nigeria. The Andoni people refer to God as Awaji or Owaji.
Historically, the Andoni (Idoni or Indo) before the colonial era had commercial contacts with European traders and with other Ijaw clans, such as the Bonny, Okrika, Kalabari, and Nkoro. The Andoni frequently fought wars with the Kingdom of Bonny. The Andoni people speak Obolo as the only native language after the complete loss their defaka Ijaw dialect. Obolo language is now a combination of Efik, Ibibio, Oron, and Ijaw dialects based on the original Ijaw intonation and Efik-Ibibio lexicon. Andoni villages and towns are situated on islands.
