Liú Yì 劉廙 (180–221), zì Gōngsì 恭嗣, was a late Hàn / early CáoWèi 曹魏 statesman and zǐ-house writer, a native of Nányáng 南陽 Ānzhòng 安眾 (modern Hénán). His biography is preserved as an appendix to Wáng Càn’s 王粲 biography in Sānguó zhì 三國志 j. 21; the dates 180–221 follow the Sānguó zhì notice (he died at forty-two sui, of illness). He came south to Jīngzhōu 荊州 in the late Hàn under Liú Biǎo 劉表, then transferred to Cáo Cāo after Cáo’s southward campaign. He served as Secretarial Court Gentleman (尚書郎) under Cáo Cāo and rose to Imperial Counsellor under Cáo Pī 曹丕 (Wéndì of Wèi). When his younger brother Liú Wěi 劉偉 joined Wèi Fěng’s 魏諷 conspiracy in 219, Liú Yì was sentenced to die but was personally pardoned by Cáo Cāo on account of his ability and reputation.
He is principally remembered for his political-philosophical writings — chiefly the Zhènglùn 政論 in 5 juàn — and for the substantial corpus of memorials, letters and biàn 辨 (discussion) prose preserved in Sānguó zhì commentary and in Quán hòu Hàn wén j. 96. In the Kanripo corpus he is the attributed author of KR3a0140 Liú Shǐ zhènglùn 劉氏政論. CBDB has no entry.
