Hóng Zīkuí 洪咨夔 (1176–1236), zì Shùnyú 舜俞, hào Píngzhāi 平齋, was a Southern Sòng official, remonstrator, and poet from Yúqián 於潛 (Línān prefecture, modern Líng’ān, Zhèjiāng). He passed the jìnshì examination in Jiātài 2 (1202) — corrected by the Sìkù editors against the Sòngshǐ “Jiādìng 2” reading on the basis of the cyclical rénxū date in his own poetry. He served in a series of provincial and capital posts, became Censor (御史) and cānzhī zhèngshì 參知政事 under Lǐzōng, and is most celebrated for his unyielding remonstrances against the dominant chief councillor Shǐ Míyuǎn 史彌遠 — one of the few late-Sòng ministers willing to challenge Shǐ openly. His collected works are Píngzhāi jí 平齋集 KR4d0311 (32 juǎn) and Píngzhāi cí 平齋詞 KR4j0046 (1 juǎn); he also wrote a Hóngshì Chūnqiū shuō 洪氏春秋說 KR1e0051 (catalogued under his name with character variant 洪咨虁 in the krp index).
