Sex trafficking in Singapore is human trafficking for the purpose of sexual exploitation and slavery that occurs in the Republic of Singapore. Singapore is primarily a destination country for sexually trafficked persons.
Sex trafficking victims in the country are from all ethnic groups in Singapore and foreigners.  Singaporean citizens and foreigners, primarily women and girls, have been deceived,     threatened,  and forced into prostitution    and unfree labour.  They are often forced to wear revealing clothing and high heels.  Many come from poverty and have little education.   Perpetrators confiscate their passports  and other documents  and guard or lock-up the women and girls.  Some force them to sign phony contracts in a foreign language they cannot read.  Sex trafficked victims experience physical and psychological trauma.   Abuse is prevalent   and they contract sexually transmitted diseases from rapes without condoms.  Malnutrition and food deprivation also occur.  A number have depression  and suicidal thoughts because of the trauma.  Some are coerced to become sex traffickers themselves. 
Sex trafficking and exploitation is not as big of a problem as it was back in the 1970s and 1980s, but it manifests in various forms throughout Singaporean society. Male and female perpetrators in Singapore come from diverse backgrounds. A number of traffickers are members of or facilitated by criminal syndicates and gangs.   Perpetrators are increasingly using websites and messaging apps to lure victims. 
The government of Singapore has been criticised for not having adequate victim protection efforts.
