Liú Yīqīng 劉一清 (fl. early Yuán) was a man of Lín’ān 臨安 (the former Southern-Sòng capital, modern Hángzhōu). His career and dates are not preserved. He is known solely from his one substantial work, the Qiántáng yíshì 錢塘遺事 KR2e0018, a 10-juǎn loyalist-critical compilation of the political and cultural history of the late Southern Sòng. The Sìkù compilers infer from internal stylistic evidence — the alternation between Sòng-loyalist and Yuán-subject diction, the heavy unattributed harvesting from late-Sòng bǐjì (especially Luó Dàjīng’s Hèlín yùlù 鶴林玉露), and the marginal lament over the choice of Hángzhōu over Jiànkāng — that he was an early-Yuán Sòng yímín (loyalist).
