Angola–Brazil relations (Portuguese: Relações Angola-Brasil) are the bilateral relations between Angola and Brazil. As former Portuguese colonies, Angola and Brazil share many cultural ties, including language (Portuguese is the official language of both countries) and religion (a majority of both countries are Roman Catholics). Both nations are members of the Community of Portuguese Language Countries, Group of 77 and the United Nations.
In southwestern Africa, Portuguese Angola was a historical colony of the Portuguese Empire (1575–1951), the overseas province Portuguese West Africa of Estado Novo Portugal (1951–1972), and the State of Angola of the Portuguese Empire (1972–1975). The People's Republic of Angola became independent in 1975 until 1992, when the country officially changed to the "Republic of Angola" as a multi-party democratic republic. Brazil was the first country to recognize Angola's independence.
In the 16th and 17th century, Portugal ruled along the coast and engaged in military conflicts with the Kingdom of Kongo, but in the 18th century, Portugal gradually managed to colonise the interior highlands. Other polities in the region included the Kingdom of Ndongo, Kingdom of Lunda, and Mbunda Kingdom. Full control of the entire territory was not achieved until the beginning of the 20th century, when agreements with other European powers during the Scramble for Africa fixed the colony's interior borders.
