The Immorality Act is the name given to two acts of the Parliament of South Africa which prohibited, amongst other things, sexual relations between white people and people of other races. They were in force between 1927-1985, and finally repealed in 2007.

The two acts are: The Immorality Act, 1927 (Act No. 5 of 1927)[1] and The Immorality Act, 1957 (Act No. 23 of 1957; subsequently renamed the Sexual Offences Act, 1957)[], the latter also acquiring a series of amendments over the years.[2]

These acts have been a major source of contention in the country, and occur as central themes in numerous South African novels, plays and films in the 20th century and thereafter.
