Huì Shìqí 惠士奇 (1670–1741), zì Zhòngrú 仲孺, hào Bànnóng 半農, was a Kāngxī-Yōngzhèng-period Yìjīng and Lǐ-classics scholar from Wúxiàn 吳縣 (Sūzhōu 蘇州, Jiāngsū 江蘇), the second-generation founder of the great Sūzhōu Huì-family Hàn-school Yìxué tradition. He was the son of Huì Zhōuti 惠周惕 (also a Hàn-school Yì scholar) and the father of the more famous Huì Dòng 惠棟 (1697–1758), the principal Wú pài 吳派 kǎozhèng master.
He passed the jìnshì in Kāngxī jǐchǒu 康熙己丑 = 1709 and held office as Hànlín Reader-in-Waiting (Hànlín yuàn shìdú 翰林院侍讀). His main Yì work is the Huìshì Yì shuō 惠氏易說 (KR1a0144) in six juàn — the first major Qīng-period reconstruction of Hàn-school Yìxué through systematic citation of Hàn-period commentators (Yú Fān 虞翻, Jīng Fáng 京房, Mèng Xǐ 孟喜, Zhèng Xuán 鄭玄). Together with his son Huì Dòng’s Yì Hàn xué 易漢學 and Yì lì 易例, the work establishes the eighteenth-century Wú pài return to the Hàn Yì-method.
His other major works include the Lǐ shuō 禮說 (a parallel work on the Lǐ-classics) and the Chūnqiū shuō 春秋說.
