port town, Akwa Ibom state, southern Nigeria. The town lies near the mouth of the Imo (Opobo) River. Situated at a break in the mangrove swamps and rain forest of the eastern Niger River delta, it served in the 19th century as a collecting point for slaves. In 1870 Jubo Jubogha, a former Igbo (Ibo) slave and ruler of the Anna Pepple house of Bonny (28 miles 【45 km】 west-southwest), came to Ikot Abasi and founded the kingdom of Opobo, which he named for Opobo the Great, a Pepple king (reigned 1792–1830). Also called Chief Jaja by Europeans, he destroyed the economic power of Bonny and made Opobo the leading power of the eastern Niger delta oil-palm trade until he was deported in 1887 by the British, who established a trading post at Opobo Town, 4 miles (6 km) southwest, on the west bank of the Imo River.

Modern Ikot Abasi serves as a trading centre for the yams, cassava (manioc), fish, palm produce, corn (maize), and taro produced by the Ibibio people of the area; it also is known for boatbuilding, although a sandbar partially blocks the entrance to its port from the Gulf of Guinea. The town is linked by highway to Aba and Port Harcourt. Pop. (2006) local government area, 132,023.
