Krai Thong or Kraithong (Thai: ไกรทอง, pronounced [krāj.tʰɔ̄ːŋ]) is a Thai folktale, originating from Phichit Province. It tells the story of Chalawan, a crocodile lord who abducts a daughter of a wealthy Phichit man, and Kraithong, a merchant from Nonthaburi who seeks to kill Chalawan. The story was adapted into a play (lakhon nok), credited to King Rama II (r. 1809–1824),[1] and has seen various modern adaptations.
