Akakio Tematereikura (died 1869) was the Prince Regent of the Polynesian island of Mangareva and other territories of the Gambier Islands, including Akamaru, Aukena, Taravai and Temoe, in 1869. He served as regent and de facto monarch during the interregnum period when the royal succession of Mangareva was in doubt. His name is also written as Akakio Matereikura in some French sources.
