Supayalay (Burmese: စုဖုရားလေး; 1863 – 25 June 1912) was a junior queen consort of the Konbaung dynasty, and was married to her half-brother Thibaw Min, the last monarch in the dynasty, in 1878.

[6] Her marriage was never consummated, and Supayalat was said to have forced monogamy on a Burmese king for the first and the last time in history, even though Thibaw also subsequently married her eldest sister Hteik Supayagyi.

The royal family's reign lasted just seven years when Thibaw Min was defeated in the Third Anglo-Burmese War and forced to abdicate by the British in 1885.

On 25 November 1885 they were taken away in a covered carriage, leaving Mandalay Palace by the southern gate of the walled city along the streets lined by British soldiers and their wailing subjects, to the River Irrawaddy where a steamboat called Thuriya (Sun) awaited.

They were exiled to the remote coastal town of Ratnagiri in India, where they lived for over 30 years.
