Suphankanlaya was a 16th-century Siamese princess who was a queen consort of King Bayinnaung of Burma. There are very few historical records of her life, but legends about her are widespread in Thailand. Many Thais revere her as a national heroine or even as a popular deity.

Bayinnaung Kyawhtin Nawrahta was king of the Toungoo Dynasty of Myanmar from 1550 to 1581. During his 31-year reign, which has been called the "greatest explosion of human energy ever seen in Burma", Bayinnaung assembled the largest empire in the history of Southeast Asia, which included much of modern-day Myanmar, the Chinese Shan states, Lan Na, Lan Xang, Manipur and Siam.
