Thiri Maha Sanda Dewi (Burmese: သီရိမဟာစန္ဒာဒေဝီ, pronounced [θìɹḭ məhà sàɴdà dèwì]; Pali: Sirimahāsandādevī) was a principal queen consort of King Mingyi Nyo of Toungoo Dynasty.
She was born in Salin where her father Thado Dhamma Yaza was viceroy and ruled ten towns of central Burma (present-day Magwe Region).
[3] Her life at Ava ended a year after Minkhaung II's death in April 1501.
Mingyi Nyo was never more than a nominal vassal, and on 16 October 1510 formally declared independence.
On 11 April 1511,[5] Mingyi Nyo held his coronation ceremony, in which he bestowed Min Hla Htut the title of Thiri Maha Sanda Dewi.
