The Sexual Offences Act, 1957 (Act No. 23 of 1957, originally the Immorality Act, 1957) is an act of the Parliament of South Africa which, in its current form, prohibits prostitution, brothel-keeping and procuring, and other activities related to prostitution. Before the law relating to sex offences was consolidated and revised by the Criminal Law (Sexual Offences and Related Matters) Amendment Act, 2007, it also prohibited various other sex offences, including sex with children under the age of consent and sex with the mentally incompetent. As the Immorality Act it was infamous for prohibiting sex between a white person and a person of another race, until that prohibition was removed by a 1985 amendment.
