Gù Yí 顧夷 (fl. mid 4th century), zì Jūnqí 君齊, was an Eastern Jìn 東晉 classicist of the prominent Wújùn 吳郡 Gù 顧 lineage — the same lineage that produced the Wú minister Gù Yōng 顧雍 (168–243). He is mentioned briefly in the Jìn shū 晉書 and in scattered notices in Tōng diǎn 通典 and Shìshuō xīnyǔ commentary. The Suí shū jīngjí zhì 隋書經籍志 records his Yìxùn 義訓 and a Sūnzǐ bīngfǎ zhù 孫子兵法注. His precise birth and death years are not preserved; he is conventionally placed in the middle of the 4th century.
In the Kanripo corpus he is the attributed author of KR3a0128 Gùzǐ yìxùn 顧子義訓. CBDB has no entry.
