Edmund Maduabebe Daukoru (born 13 October 1943) is a former Nigerian Minister of State for Energy and was Secretary General of the Organization of the Petroleum Exporting Countries (OPEC) in 2006.

He was employed by Shell International Petroleum Company from 1970, where he rose from Chief Geologist to General Manager of Exploration in Nigeria.

[4] Daukoru was appointed the Amayanabo, or traditional ruler of Nembe Kingdom in Bayelsa state, taking the name Mingi XIII.

[5] Rivalries between the Bassambiri and Ogbolomabiri communities of the old Nembe Kingdom date back over 200 years.

In April 2010 the Bayelsa State government attempted once more to resolve these issues, bringing together Daukoru with Ralph Iwowari, Amanyanabo of Nembe Bassambiri, and other chiefs to find a solution.
