Dù Yí 杜夷 (258–323), zì Xíngqí 行齊, was a Western and Eastern Jìn 晉 classicist and recluse-scholar, a native of Lújiāng 廬江 Qiánxiàn 灊縣. His biography is in Jìn shū 晉書 j. 91 (Rúlín lièzhuàn); the dates follow the Jìn shū notice. He was famous in his own day for repeatedly declining offers of high office — from Sīmǎ Lún 司馬倫, Sīmǎ Yǐng 司馬穎, and (after the southward retreat of 317) the Eastern Jìn court itself — and for sustaining an austere life of scholarship and meditation. Eventually persuaded to take low-ranking office in the late Eastern Jìn court, he held the post of zhōngshū lìng 中書令 only briefly.
His writings included classical commentaries (recorded in the Suí shū jīngjí zhì) and the zǐ-house treatise Yōuqiú zǐ 幽求子 (also given as Yōuqiú xīnshū 幽求新書). In the Kanripo corpus he is the attributed author of KR3a0136 Dù Shǐ yōuqiú xīnshū. CBDB has no entry.
