Okrika is an island in Rivers State, Nigeria, capital of the Local Government Area of the same name. The town is situated on an island south of Port Harcourt, making it a suburb of the much larger city.

The average elevation of Okrika is 452 metres. It lies on the north of the Bonny River and on Okrika Island, 35 miles (56 km) upstream from the Bight of Bonny. The town can be reached by vessels of a draft of 29 feet (9 metres) or less.

Formerly a fishing village of the Ijo (Ijaw) people in the mangrove swamps of the eastern Niger River(Delta), Okrika became the capital of the Okrika kingdom in the early 17th century and actively dealt in slaves. It served as a port for the exportation of palm oil after the abolition of the slave trade in the 1830s, but it was a less significant port facility than either Bonny (18 miles [46 km] south) or Opobo (32 miles [81 km] east-southeast). By 1912, Okrika had been completely eclipsed by Port Harcourt, and it was not revived as a commercial town until 1965, when the nearby Port Harcourt refinery was completed and pipelines were built to a jetty on Okrika Mainland. It also has a major gas plant facility (Alakiri gas plant) that supplies to the refinery and others.
