Shin Sawbu was queen regnant of Hanthawaddy from 1454 to 1471. Queen Shin Sawbu is also known as Binnya Thau or Old Queen in Mon. Queen Shin Sawbu and Queen Jamadevi of Haripunjaya are the two most famous among the small number of queens who ruled in mainland Southeast Asia.

The Hanthawaddy Kingdom was the polity that ruled lower Burma (Myanmar) from 1287 to 1539 and from 1550 to 1552. The Mon-speaking kingdom was founded as Ramaññadesa by King Wareru following the collapse of the Pagan Empire in 1287 as a nominal vassal state of the Sukhothai Kingdom and of the Mongol Yuan dynasty. The kingdom became formally independent of Sukhothai in 1330 but remained a loose federation of three major regional power centres: the Irrawaddy Delta, Bago, and Mottama. Its kings had little or no authority over the vassals. Mottama was in open rebellion from 1363 to 1388.
