Hán Bāngqí 韓邦奇 (1479–1555), zì Rǔjié 汝節, hào Yuànluò 苑洛, posthumous title Gōngjiǎn 恭簡, was a mid-Míng official, Yìxué scholar, and music-theorist from Cháoyì 朝邑 (Xī’ān 西安, Shǎnxī 陝西). He passed the jìnshì examination in Hóngzhì rénxū 弘治壬戌 = 1502 and rose through provincial and court appointments to become Minister of War at Nánjīng (Nánjīng Bīngbù shàngshū 南京兵部尚書). His biography is in the Míng shǐ 明史.
His scholarly work spans the Yì, music theory, and astronomy. The Qǐméng yìjiàn 啟蒙意見 (KR1a0094), composed when he was a young scholar in 1503 (self-preface dated Hóngzhì 16, second month), is a structured exposition of Zhū Xī’s Yì xué qǐ méng 易學啟蒙 (KR1a0035) in five sections corresponding to Zhū’s own chapter divisions. He also wrote the Yuànluò zhì lè 苑洛志樂, an extensive treatise on music and harmonics that survives in the Sìkù.
His elder brother Hán Bāngjìng 韓邦靖 was also a Yìxué scholar; the two brothers, with their cousin Wáng Yáng 王陽 (no relation to Wáng Yángmíng 王陽明), formed the core of an early-sixteenth-century Shǎnxī Lǐxué circle.
