Wáng Yòupǔ 王又樸 (1681–1760), zì Jièshān 介山, was a Yōngzhèng-Qiánlóng-period official and Yìjīng scholar from Tiānjīn 天津. He passed the jìnshì in Yōngzhèng guǐmǎo 雍正癸卯 = 1723 and was selected as shù jí shì 庶吉士 (junior Hànlín scholar); he held office through Sub-Prefect of Lúzhōu 盧州 (modern Anhuī).
His main work in the Sìkù is the Yì yì shù xìn 易翼述信 (KR1a0151) in twelve juàn — a Qiánlóng-period Yìjīng commentary that takes the Ten Wings as the principal interpretive authority for the canonical scripture. The title is programmatic: shù xìn — “transmitted in faith” — signals Wáng’s commitment to following the Confucian Wings against any later doctrine (including Zhū Xī’s reading that the Wings might not exhaust the Yì’s original meaning). The work draws extensively on Lǐ Guāngdì 李光地 (李光地), whose readings are most numerous in the cited apparatus, alongside Zhū Xī’s Běnyì (with selective divergence). Methodologically the work avoids the chart-tradition entirely, listing the HétúLuòshū / prior-and-posterior-heaven discussions as appendix to the volume’s miscellaneous discussions rather than at the head.
