The following is a list of 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 later by South Africa.
The title of the position changed a number of times. Under German rule, the title of the position went from Commissioner (1884–1893) to Provincial Governor (Landeshauptleute) (1893–1898) to Governor (1898–1915). Under South African rule, the title was Administrator from 1915–1977 and Administrator-General from 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.
