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.
Prior to her brief reign as regent, she had been a close adviser of her brother since 1369, and the de facto ruler of the kingdom since the early 1380s. But she never gained the support of the court. Powerful factions of the court used her alleged long-term affair with her much younger nephew-in-law Smin Maru to undermine her influence. When her nephew and adopted son Binnya Nwe raised a rebellion in 1383, Chief Minister Zeik-Bye secretly sided with Nwe.
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.
