Máo Huǎng 毛晃 was a Southern-Sòng Shàngshū-and-philological scholar from Qúzhōu 衢州 (modern Zhèjiāng 浙江), active circa Lóngxīng 隆興 (1163–1164) — the catalog meta gives his attested period as fl. 1162. He is best known as the principal compiler of the Zēngxiū hùzhù lǐbù yùnlüè 增修互注禮部韻略 (an expanded Yùnlüè phonological dictionary, in the xiǎoxué class).
His one Shàngshū work in the Sìkù is the Yǔ gòng zhǐ nán 禹貢指南 (KR1b0008) in four juàn — a focused commentary on the Yǔ gòng 禹貢 chapter of the Shàngshū, the foundational document of Chinese historical geography. Methodologically the work draws extensively on the medieval geographical tradition (Ěr yǎ 爾雅, the Jìn dìlǐ zhì 晉地理志, the Jiǔ yù zhì 九域志) to anchor the Yǔ gòng’s Nine Regions in concrete administrative geography.
