This article lists the administrators of former South African provinces. It encompasses the period from 1910 to 1994, when South Africa was divided into four provinces: Cape Province, Natal Province, Orange Free State Province and Transvaal Province. Before the provinces were created, the area was divided into four British colonies: Cape Colony, Natal Colony, Orange River Colony and Transvaal Colony.
The provinces were established as a result of the creation of the Union of South Africa in 1910, and disestablished after the Republic of South Africa held the first post-apartheid general election in 1994.
