Wáng Jūnyù 王君玉 (fl. early-to-mid eleventh century) is the conventional name under which the Northern-Sòng bǐjì Guólǎo tányuàn 國老談苑 (KR3l0052) circulates in late and modern editions. The attribution is in fact insecure: the earliest catalog evidence (Chén Zhènsūn’s 陳振孫 Zhízhāi shūlù jiětí 直齋書錄解題 and the Sòng shǐ Yìwén zhì 宋史藝文志) records the work under the title Guólǎo xián tán 國老閒談 and gives the author only as Yímén Jūnyù 夷門君玉 — “Jūnyù of Yímén” — without a surname. The Sìkù quánshū zǒngmù tíyào compilers accordingly concluded that the surname “Wáng” was added by later (likely Míng) editors when the title was also reshaped from 閒談 to 談苑. Yímén 夷門 is a classical alias for the Northern-Sòng capital Kāifēng 開封, deriving from the eastern gate of the Warring-States Wèi 魏 capital Dàliáng 大梁; it therefore locates the author in or in the orbit of the metropolitan literati, but supplies no further biographical detail. The supplementary hào 號 yǐnsǒu 隱叟 (“recluse-elder”) suggests an old retired official rather than a serving courtier.
The composition window of Guólǎo tányuàn — which contains material running into the very end of Zhēnzōng’s reign and the early Rénzōng (the disgrace of Dīng Wèi 丁謂 in 1022, the demotion of Wáng Qīnruò 王欽若) but no Rén-zōng-period court business — places the author’s literary activity c. 1022–1063, most plausibly in the Tiānshèng 天聖 — Jǐngyòu 景祐 decade (1023–1037). The CBDB contains two persons named Wáng Jūnyù (ids 22230 and 101207): id 22230 is a Northern-Sòng figure whose four sons are mentioned in a mùbiǎo 墓表 funerary inscription drafted by Wáng Ānshí 王安石, of which only one son (Wújiǔ 無咎) actually held the jìnshì degree; chronologically this Wáng Jūnyù is plausible but cannot be securely linked to the bǐjì. Id 101207 is a Yuán-period figure and is excluded on dynastic grounds. The CBDB id is therefore left blank pending firmer evidence.
The author has no other works in the Kanripo corpus.
