The Ijaw people, otherwise known as the Ijo people, are an ethnic group found in the Niger Delta in Nigeria, with significant population clusters in Bayelsa, Delta, and Rivers. They also occupy Edo, Ondo, and small parts of Akwa Ibom. Many are found as migrant fishermen in camps as far west as Sierra Leone and as far east as Gabon. They account for about 1.8% of the Nigerian population according to CIA Factbook. The Ijaws are one of the most populous tribes inhabiting the Niger Delta region and the eighth largest ethnic group in Nigeria.

It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states from South East geopolitical zone.
