The Immorality Act, 1927 (Act No. 5 of 1927) was an act of the Parliament of South Africa that prohibited extramarital sex between white people and people of other races. In its original form it only prohibited sex between a white person and a black person, but in 1950 it was amended to apply to sex between a white person and any non-white person. The act was repealed by the Immorality Act, 1957, section 16 of which contained a similar prohibition of sex between whites and non-whites. The prohibition was finally lifted by the Immorality and Prohibition of Mixed Marriages Amendment Act, 1985.
