Maha Dewi (Burmese: မဟာဒေဝီ, pronounced [məhà dèwì]; c. 1322 – c. 1392) was princess-regent of Hanthawaddy for about ten weeks at the end of her brother King Binnya U's reign. She was also governor of Dagon from 1364 to c. 1392. Her ailing brother formally handed her power in October 1383. She could not defeat Nwe's rebellion. After Binnya U's death two months later, the court chose Nwe, who ascended the throne with the title of Razadarit. The new king reappointed his adoptive mother to her old post at Dagon but purely in a ceremonial role.
