Thado Dhamma Yaza I of Prome

Thado Dhamma Yaza I (Burmese: သတိုးဓမ္မရာဇာ, pronounced [ðədó dəma̰ jàzà]; c. 1490s–1551) was viceroy of Prome (Pyay) from 1542 to 1550 during the reign of his son-in-law King Tabinshwehti of Toungoo Dynasty of Burma (Myanmar), and the self-proclaimed king of the city-state from 1550 to 1551. After the death of Tabinshwehti in 1550, the man who started out as a royal household servant of Tabinshwehti in 1516 declared himself king of Prome with the style of Thado Thu (သတိုးသူ, [ðədó θù]), and did not submit to Bayinnaung, Tabinshwehti's chosen successor. His fortified city-state fell to Bayinnaung's forces in 1551 after a six-month battle. He was executed on the order of Bayinnaung, who later regretted the decision.

In Thai history, he is identified as the commander who slew Queen Suriyothai on her war elephant during the first Burmese invasion of Siam.
