Piya Yaza Dewi (Burmese: ပီယရာဇဒေဝီ, pronounced [pìja̰ jàzà dèwì]; Pali: Piyarājadevī; c. 1360s – c. April 1392) was the chief queen consort of King Razadarit of Hanthawaddy Pegu from 1384 to 1392.

According to the Razadarit Ayedawbon chronicle, the future queen was a commoner named Mwei Maneit (မွေ့ မနိတ်; "Miss Ruby").

Her husband fled to Pegu, and reported the news to Princess Maha Dewi, the prince's aunt and adoptive mother.

At Pegu, Prince Binnya Nwe's first wife, Tala Mi Daw, who had just given birth to their first child Bawlawkyantaw, was deeply hurt.

[3] In response, Nwe held the coronation ceremony the next day, 5 January 1384,[note 4] with Maneit as his chief queen.

[4] The young king's relationship with his first wife never recovered, and Piya Yaza Dewi remained the chief queen.
