Maung Minbyu (Burmese: မောင်မင်းဖြူ [màʊɰ̃ mɪ́ɰ̃ bjù]) is one of 37 nats (spirits) in the official Burmese pantheon of nats.^[1]

Maung Minbyu is identified with several historical figures. One version suggests he was an unnamed prince of Ava who married the daughter of a cavalry commander. He died from overuse of opium. In another version, he was the reincarnation of Bawlawkyantaw, the son of Razadarit, the king of Hanthawaddy, who was executed by his father when he was only about seven years old. He is also identified with the Crown Prince Minye Kyawswa, and son of Minkhaung I of Ava Kingdom. The fiery prince, whose birth name was Min Phyu (or Minbyu), died of wounds in the Forty Years' War in March 1415.^[2]
