Elobey, Annobón, and Corisco was a colonial administration of Spanish Africa consisting of the island of Annobón, located in the Gulf of Guinea, and the small islands of Elobey Grande, Elobey Chico and Corisco, located in the Bay of the Mitémélé River. It was established as a protectorate in 1843. Its total area was under 36 km2, and the estimated population in 1910 was 2,950 people. The capital was Santa Isabel. The islands are presently part of Equatorial Guinea. Elobey Grande, Elobey Chico and Corisco are now part of the Litoral Province within the Río Muni (mainland) of Equatorial Guinea, while Annobón constitutes a province in its own right within the Insular Region.
