In Malay ghost beliefs, the Orang Minyak is a supernatural creature coated with shiny black grease who abducts young women by night. 'Orang Minyak' literally means oily man in Malay.

According to the legend, the creature is able to climb walls and grab victims while evading. According to some folklorists, the Orang Minyak has been alternatively described as appearing naked, or wearing a black pair of swimming trunks. A number of stories describe the Orang Minyak as a rapist that only targets virgins. It has been traditionally blamed for rapes, beginning in the 1950s.

Some versions of the legend hold that the Orang Minyak is an evil human warlock rather than a supernatural creature. In one version of the legend, popularised in the 1958, the Orang Minyak was a man who was cursed in an attempt to win back his love with magic. According to the story, the Devil offered to help the creature and give him powers of the black arts, but only if the Orang Minyak worshipped him and raped 21 virgins within a week.

Malaysian newspapers occasionally report claimed sightings of the Orang Minyak. In 2012, the residents in Kampung (village) Laksamana, in Gombak, Selangor, Malaysia, claimed to have seen and heard the creature.
