Nana Olomu (1852–1916) was an Itsekiri chief, palm oil merchant, freedom fighter and Governor of the Benin River from 1886 to 1894.
Born in Jakpa to Chief Olomu (1810-1884), who had 59 wives and 106 children (53 male and 53 female), Nana Olomu successfully prevented European penetration of the hinterland of the Benin and the nearby rivers until he was captured and sent to exile in Accra in 1894.
Nana Olomu's monopolistic control of trade in the Benin River stifled Urhobo traders and Europeans who now have their share of the trade significantly reduced. He signed a treaty on behalf of his people in 1884 that gave the British rights over Itsekiri. By this treaty, Itsekiri became the first protectorate in the Western Niger Delta, few years before the successive fall of Oba Nogbaisi Ovonramwen of the Benin Kingdom. Olomu was oblivious of a section of the treaty which ended the sovereignty of Itsekiri.
