巴基道（缅甸语：ဘကြီးတော်，Bagyidaw，1784年－1846年10月），又名实皆王，中国史料称其为弗极道或孟既，是缅甸贡榜王朝的一位国王，1819年至1837年在位。他是波道帕耶（孟云）之孙、扎多敏梭之子。在位期间，王朝势力范围曾扩达今缅甸大部分与阿萨姆阿豪姆王国。

1826年，为了港口控制权，他展开与英国为期三年的第一次英缅战争，虽成功抵抗英国入侵，且僵持不下，最后被迫与英国签订了不平等的扬达波条约,失去德林达依省（Tanintharyi）及印缅边境，（旧名「丹那沙林」（Tenasserim））。

Bagyidaw (Burmese:ဘကြီးတော်, pronounced: [ba̰dʑídɔ̀]; also known as Sagaing Min, [zəɡáiɴ mɪ́ɴ]; 23 July 1784 – 15 October 1846) was the seventh king of the Konbaung dynasty of Burma from 1819 until his abdication in 1837. Prince of Sagaing, as he was commonly known in his day, was selected as crown prince by his grandfather King Bodawpaya in 1808, and became king in 1819 after Bodawpaya's death. Bagyidaw moved the capital from Amarapura back to Ava in 1823.
