Manisanda Khin U (Burmese: မဏိစန္ဒာ ခင်ဦး [mənḭsàɰ̃dà kʰɪ̀ɰ̃ ʔú]) was queen to three consecutive kings of Pagan dynasty of Burma (Myanmar).
The ethnic Mon queen is famous in Burmese history for her love triangle with Gen. Kyansittha and King Anawrahta.
Circa early 1070s, her father gave the princess to Anawrahta as gratitude for Pagan's help in repelling attacks on Pegu by foreign invaders from the direction of Chiang Mai.
Kyansittha, who led the Pagan army that drove out the invaders, rode alongside the lady Manisanda who was borne in a curtained litter.
The king nearly killed Kyansittha, and banished his adopted son and best general for the rest of his reign.
