Zhào Yànwèi 趙彥衞 (also written 趙彥衛; fl. 1190s–1206; CBDB id 14680), zì Jǐngān 景安, was a Southern Sòng official-scholar of the imperial Zhào clan. Shàoxī period (1190–1194) he was zǎi (subprefect) of Wūchéng 烏程, then tōngpàn (Vice-Prefect) of Huīzhōu; by Kāixǐ 2 (1206) he was Xīnān jùnshǒu (prefect of Huīzhōu, the same Xīnān commandery) — his preface to Yún lù màn chāo of that year is so signed at the Huángshāntáng. His one surviving work is the Yún lù màn chāo 雲麓漫抄 (KR3j0117) — originally titled Yōng lú xián jì 擁鑪閒記 in 10 juàn, printed at the Hàndōng xuégōng (school) when he served there, then expanded to 15 juàn on his transfer to Xīnān, with the additional 5 juàn printed in the prefectural office and the title changed to Yún lù màn chāo. The book contains kǎozhèng-and-anecdote material on Sòng bǐjì-style topics; the Wénxiàn tōngkǎo records it as 20 juàn + a 2-juàn sequel (possibly a misprint, or a later expansion). The book is notable for its discussion of the now-lost Lǚ Dàfáng 呂大防 Chángān tú (map of Chángān), the Táng zhìkē (decree-examination) typology, and the cost-accounting of Sòng receptions of Jīn embassies — all otherwise undocumented in the histories.
