The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is typically considered to be 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. Of all the states that the region covers, only Cross River is not an oil-producing state.

Delta State is an oil and agricultural producing state in Nigeria. It is situated in the region known as the South-South geo-political zone with a population of 4,112,445. The capital city is Asaba, located at the northern end of the state, with an estimated area of 762 square kilometres (294 sq mi), while Warri is the economic nerve center of the state and also the most populated. It is located in the southern end of the state. The state has a total land area of 16,842 square kilometres (6,503 sq mi).

The Movement for the Emancipation of the Niger Delta (MEND) is one of the largest militant groups in the Niger Delta region of Nigeria.

The Niger Coast Protectorate was a British protectorate in the Oil Rivers area of present-day Nigeria, originally established as the Oil Rivers Protectorate in 1884 and confirmed at the Berlin Conference the following year. It was renamed on 12 May 1893, and merged with the chartered territories of the Royal Niger Company on 1 January 1900 to form the Southern Nigeria Protectorate.

The Niger Delta Basin, also referred to as the Niger Delta province, is an extensional rift basin located in the Niger Delta and the Gulf of Guinea on the passive continental margin near the western coast of Nigeria with suspected or proven access to Cameroon, Equatorial Guinea and São Tomé and Príncipe. This basin is very complex, and it carries high economic value as it contains a very productive petroleum system. The Niger delta basin is one of the largest subaerial basins in Africa. It has a subaerial area of about 75,000 km2, a total area of 300,000 km2, and a sediment fill of 500,000 km3. The sediment fill has a depth between 9–12 km. It is composed of several different geologic formations that indicate how this basin could have formed, as well as the regional and large scale tectonics of the area. The Niger Delta Basin is an extensional basin surrounded by many other basins in the area that all formed from similar processes. The Niger Delta Basin lies in the south westernmost part of a larger tectonic structure, the Benue Trough. The other side of the basin is bounded by the Cameroon Volcanic Line and the transform passive continental margin.

The Niger Delta red colobus is a critically endangered species of colobus monkey endemic to the western part of the Niger Delta. It is threatened by hunting and habitat loss.

The Nigerian Ports Authority (NPA) is a federal government agency that governs and operates the ports of Nigeria.
