Kinwon Min Gyi (Burmese: ကင်းဝန်မင်းကြီး ဦးကောင်း; 1831 - 1918) was a minister under King Mindon's and King Thibaw's reigns. He attempted to westernise the Burmese kingdom's existing bureaucracy into a more democratic system. Because of such attempts to do so, Kinwun Min Gyi was accused by many to have allowed Britain to win the Third Anglo-Burmese War.
Kinwon Min Gyi was born U Kaung. King Mindon, upon Crown Prince Ka Naung's assassination, named U Kaung a diplomat, and was renamed Kinwon Min Gyi U Kaung. In 1881, he led the first Burmese diplomatic group to Europe. After King Mindon's death, Kinwon Min Gyi lost much power. He ordered the Burmese troops during the Third Anglo-Burmese War to not attack invading British. U Kaung's role in the initial collapse of Burmese resistance later gave rise to the popular mnemonic U Kaung lein htouk, minzet pyouk ("U Kaung's treachery, end of dynasty": U=1, Ka=2, La=4, Hta=7 in Burmese numerology i.e. Burmese Era 1247 or 1885AD).
Under British colonial rule, Kinwon Min Gyi served as a civil servant in administration, writing many famous books and poems in Burmese literature.
