This article lists the governors of British South African colonies, including the colonial prime ministers. It encompasses the period from 1797 to 1910, when present-day South Africa was divided into four British colonies namely: Cape Colony (preceded by Dutch Cape Colony), Natal Colony, Orange River Colony and Transvaal Colony.

After the colonies were disestablished as a result of the creation of the Union of South Africa, the area was divided into four provinces of the Union: Cape Province, Natal Province, Orange Free State Province and Transvaal Province.
