Angola, officially the Republic of Angola (Portuguese: República de Angola, pronounced: [ʁɨˈpublikɐ dɨ ɐ̃ˈɡɔla];Kikongo, Kimbundu, Umbundu: Repubilika ya Ngola), is a country in southern Africa bordered by Namibia on the south, the Democratic Republic of the Congo on the north, and Zambia on the east; its west coast is on the Atlantic Ocean with Luanda as its capital city. The exclave province of Cabinda has borders with the Republic of the Congo and the Democratic Republic of the Congo.

The Portuguese were present in some—mostly coastal—points of the territory of what is now Angola, from the 16th to the 19th century, interacting in diverse ways with the peoples that lived there. In the 19th century they slowly and hesitantly began to establish themselves in the interior. Angola as a Portuguese colony encompassing the present territory was not established before the end of the 19th century, and "effective occupation", as required by the Berlin Conference (1884) was achieved only by the 1920s. Independence was achieved in 1975, after a protracted liberation war. After independence, Angola was the scene of an intense civil war from 1975 to 2002. The country has vast mineral and petroleum reserves, and its economy has on average grown at a two-digit pace since the 1990s, especially since the end of the civil war. In spite of this, standards of living remain low for the majority of the population, and life expectancy and infant mortality rates in Angola are among the worst-ranked in the world. At the same time, a minority has reached comfortable life standards, and the dominant stratum has succeeded in accumulating considerable wealth, so that social inequality in Angola is one of the highest in the world.
