Thao Thep Krasattri and Thao Si Sunthon

Thao Thep Krasattri (ท้าวเทพกระษัตรี) and Thao Si Sunthon (ท้าวศรีสุนทร) were styles awarded to Than Phuying Chan (ท่านผู้หญิงจัน), wife of the then recently deceased governor of Mueang Thalang, Phuket Province (also known as Junk Ceylon), and her sister, Khun Muk (คุณมุก), who defended the island in the Burmese–Siamese War (1785–1786). According to popular belief, they repelled a five-week invasion by Burmese in 1785, killing male soldiers and rallying Siamese troops.

Chan and Muk were later honored by King Rama I with the Thai honorific Thao, as Thao Thep Krasattri and Thao Si Sunthon, respectively.

The "Heroine's Monument" honouring them is situated on the main highway (402) between the Phuket International Airport and Phuket town.
