This article lists the colonial governors of South West Africa.

South West Africa was the colonial predecessor of the modern day Republic of Namibia from when the territory was controlled by the German Empire (as German South West Africa) and the Union of South Africa.

Under South African rule, the title was Administrator (1915–1977) and Administrator-General (1977–1990).

After the United Nations terminated South Africa's mandate to govern South West Africa, the UN appointed commissioners of its own.

They had no authority and South Africa refused to recognize them, and are not included here.
