The Kalabari are a sub-group of the Ijaw people living in the eastern Niger Delta region of Nigeria. Originally, they were known as the Awome. The name Kalabari was derived from their ancestor Perebo Kalabari who was a son of Meinowei. Their original settlement was spelt as Calabar by the Portuguese which was pronounced Kalabari. This settlement (town) was abandoned as the people moved to other fishing settlements. Portuguese settlers continued to maintain the name Calabari which became surrounded by the Efik people of Duke town. When the British came the word Calabari was pronounced as Calabar (Kalaba) instead of Kalabari. At this time the original Ijoid Kalabaris had moved to a new location which became the new Calabar territory since the old Calabar is occupied by different people. Old Calabar became an Efik town with time which has the name Calabar.

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.
