Sex trafficking in Malaysia is human trafficking for the purpose of sexual exploitation and slavery that occurs in Malaysia. Malaysia is a country of origin, destination and transit for sex trafficking.

Sex trafficking victims in the country are from all ethnic groups in Malaysia and foreigners. Children,^[1][2] people in rural areas and or poverty, minorities,^[3] migrants, and refugees^[4][5] are vulnerable. Malaysian citizens, primarily women and girls,^[6] have been sex trafficked into other countries in Asia and different continents.^[7] Many are forced into prostitution and or marriage^[2][8] and unfree labour.^[9] Victims are threatened and experience physically and psychologically abuse.^[3] They contract sexually transmitted diseases from rapes. Some are coerced to be in online pornographic films. The perpetrators are often part of or collude with criminal syndicates.^[10] They increasing use the internet to deceive victims.^[3][7]

The government of Malaysia has been criticized for its response to sex trafficking. Corruption and impunity are pervasive. Officials and police have been complicit in trafficking.^[9][5][11] Law enforcement have also failed to recognize victims and other indications of trafficking, and have treated cases as immigration violations.^[5] Though some anti-trafficking efforts, such as public service announcements,^[5] are carried out, progress has been limited by poor border management,^[10] weak victim protections,^[5] inadequate law enforcement practices, low convictions,^[12] and other factors.^[9]
