Portuguese Angola refers to Angola during the historic period when it was a territory under Portuguese rule in southwestern Africa. In the same context, it was known until 1951 as Portuguese West Africa (officially the State of West Africa).

The history of Portuguese presence on the territory of contemporary Angola lasted from the arrival of the explorer Diogo Cão in 1484 until the decolonization of the territory in November 1975.

Initially ruling along the coast and engaging in military conflicts with the Kingdom of Kongo, in the 18th century Portugal gradually managed to colonise the interior Highlands. However, 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. In 1975, Portuguese Angola became the independent People's Republic of Angola.
