Atula Thiri Maha Yaza Dewi (Burmese: အတုလသီရိ မဟာရာဇ ဒေဝီ [ʔətṵla̰ θìɹḭ məhà jàza̰ dèwì]; Pali: Atulasīrimahārājadevī; c. 1518–1568) was the chief queen consort of King Bayinnaung of Burma (Myanmar) from 1550 to 1568. The queen was of Toungoo royalty, daughter of King Mingyi Nyo and younger half-sister of King Tabinshwehti. She was the mother of King Nanda. Her 1534 marriage to Bayinnaung, a commoner, solidified an unfailing alliance between Tabinshwehti and Bayinnaung who together would go on to found the Toungoo Empire (or the Second Burmese Empire).
