Gāo Yòu 高誘 (fl. c. 205–212), a native of Zhuō Commandery 涿郡 (modern Héběi), was a leading philological commentator of the late Eastern Hàn. He studied under Lú Zhí 盧植 alongside Liú Bèi 劉備 and Gōngsūn Zàn 公孫瓚, and held office under the warlord administrations of the chaotic late Hàn — most notably as Magistrate of Zhuó 涿令 and as Sīkòng Yuàn 司空掾 under Cáo Cāo 曹操. His enduring legacy is in commentarial scholarship: he produced annotations to three of the most challenging late–pre-Hàn / early-Hàn philosophical and historical anthologies — the Lǚshì chūnqiū 呂氏春秋 (preface dated Jiàn’ān 10, i.e. 205), the Huáinánzǐ 淮南子, and the Zhànguó cè KR2e0003. The Zhànguó cè annotation is the only one to have transmitted only fragmentarily; it reached the Northern Sòng in just 8 of an original 20-odd juǎn, and the present Zhànguó cè circulates in the recension of 姚宏 (Sòng), who supplied xùzhù 續注 (“continued annotation”) for the juǎn whose Gāo Yòu commentary had been lost. The lifedates given in some reference works (205–212) refer only to his floruit as established by the surviving prefaces; his own birth and death years are unknown.
