Xú Shùkuí 徐述夔 (birth year unknown, d. 1762, Qiánlóng 27) was a mid-Qīng fiction writer. CBDB 63199 records only his death year (1762), citing the Qīngdài Rénwù Shēngzú Niánbiǎo (#19309).
Xú Shùkuí’s native place and official career are poorly documented. He is known primarily as the author of the novel Kuàishì Zhuàn 快士傳 (KR4k0167), a 16-juàn vernacular fiction work composed in the mid-Qiánlóng period.
He is most historically notable for the posthumous literary inquisition (wénzì yù 文字獄) that struck his family after his death. During the Qiánlóng reign, writings attributed to him — including verses alleged to contain anti-Manchu and pro-Míng allusions — became the basis for the prosecution of his son Xú Shísān 徐食三 and other family members. Xú Shùkuí’s remains were reportedly desecrated posthumously and his descendants were executed or punished. The case is among the more striking examples of the Qiánlóng-era literary inquisition targeting a writer after his death.
