Equatorial Guinea, officially the Republic of Equatorial Guinea, is a country on the west coast of Central Africa and the only Spanish-speaking country in Africa. It has an area of 28,000 square kilometres (11,000 sq mi). Formerly the colony of Spanish Guinea, its post-independence name refers to its location both near the Equator and in the African region of Guinea. As of 2025, the country has a population of 1,853,559, over 85% of whom are members of the Fang people, the country's dominant ethnic group. The Bubi people, indigenous to Bioko Island, are the second largest group at approximately 6.5% of the population. The country's new capital, since January 2026, is Ciudad de la Paz, and Malabo, the former capital, is the second largest city, after Bata.
Equatorial Guinea consists of two parts. The mainland region, Río Muni, is bordered by Cameroon to the north and Gabon to the south and east. It has the majority of the population and is the location of Bata, Equatorial Guinea's largest city, and Ciudad de la Paz, the new capital. Río Muni's small offshore islands include Corisco, Elobey Grande, and Elobey Chico. The insular region consists of the islands of Bioko (formerly Fernando Po) in the Gulf of Guinea and Annobón. Bioko Island is the northernmost part of Equatorial Guinea and is the site of Malabo. The Portuguese-speaking island nation of São Tomé and Príncipe is located between Bioko and Annobón.
The Equator through Equatorial Guinea's territorial waters, about 1.4° south of Annobón island, its southernmost territory.
Pygmies are the first confirmed inhabitants to settle in the area of present-day Equatorial Guinea, followed by a migration of Bantu-speaking groups in the 6th century BC. The Portuguese explorer Fernando Pó explored the area in 1472. Via the 1778 Treaty of El Pardo, Portugal ceded territories in the Bight of Biafra to Spain; the new territory was declared Spanish Guinea during the Scramble for Africa. Nearly 200 years later, it gained independence in 1968 under the bloody dictatorship of President Francisco Macías Nguema. He declared himself president for life in 1972, but was overthrown in a coup in 1979 by his nephew, Teodoro Obiang Nguema Mbasogo, who has served as the country's president since. Obiang's regime has also been widely characterized as a dictatorship by foreign observers.
Since the mid-1990s, Equatorial Guinea has become one of sub-Saharan Africa's largest oil producers. It has subsequently become one of the richest countries per capita in Africa; this wealth is extremely unevenly distributed, with few people benefiting from the oil riches. However, the country has the highest Human Development Index, among sub-sahariana countries (rank 133rd) only after Gabon, and 7.7% of children dying before the age of five in 2021, a continuous reduction from 17.9% in 1990.
Since Equatorial Guinea is a former Spanish colony, Spanish is the main official language. French and (as of 2010) Portuguese have also been made official. A part from the Spanish provinces in Africa (Canary islands, Ceuta, and Melilla), Equatorial Guinea is one of the two countries in Africa (the other being the partially recognized Sahrawi Arab Democratic Republic) and the only sovereign country in the same continent where Spanish is an official language. Spain supports education and research for Equatoguinean citizens, including cooperation on teachers training and postgraduate/doctoral education. Since the Spanish colonial rule, the education was highly influenced by the spanish system, and since then Equatorial Guinea has had one of the highest adult literacy rates 95.3%, and youth literacy rate 98% among the Sub-saharian African countries.
Since the United States oil companies are the main operators of the oil industry in Equatorial Guinea, they are the main supporters of Guinea's government revenue. Guinea's government is authoritarian and sultanist and has one of the worst human rights records in the world, consistently ranking among the "worst of the worst" in Freedom House's annual survey of political and civil rights. Reporters Without Borders ranks Obiang among its "predators" of press freedom. Human trafficking is a significant problem, with the U.S. Trafficking in Persons Report identifying Equatorial Guinea as a source and destination country for forced labour and sex trafficking.The country is a member of the United Nations, African Union, Francophonie, OPEC, and the CPLP.
