Prostitution in Singapore in itself is not illegal, but various prostitution-related activities are criminalized. This includes public solicitation, living on the earnings of a prostitute and maintaining a brothel. In practice, police unofficially tolerate and monitor a limited number of brothels. Prostitutes in such establishments are required to undergo periodic health checks and must carry a health card.

During the Japanese occupation of Singapore β45 , brothels were set up for the use of Japanese servicemen. There were about twenty such brothels in the city, typically housed in deserted Chinese mansions. In the s striptease acts took place at the city's getai shows, performed by specialist travelling dance troupes. During this decade the city's police organised operations to reduce prostitution and Chief Minister Lim Yew Hock sought out suggestions as to how prostitution could be limited.
