Thanbula (Burmese: သမ္ဘူလ, pronounced: [θàɴbùla̰]; Trilokavatamsika, U Sauk Pan, or Sambhula, also spelled Thambula) was a chief queen consort of King Kyansittha of the Pagan Dynasty of Burma (Myanmar). She met Kyansittha while he was in exile at Kyaungbyu, and later gave birth to Yazakumar. Kyansittha went back to Bagan (Pagan), and later became king. She found out about it only years later, and showed up at the palace gate with their son.
