A luk khrueng (Thai: ลูกครึ่ง, literally "half-child") is a colloquial Thai term referring to a person whose parents are of different nationalities. It is used mostly for people of mixed Thai and white origin. In the modern era, many luk khrueng are born of relationships and marriages when Westerners come to live and to work in Thailand or when Thai people go to study in Western or foreign countries.
