Yuán Lǎng 袁朗 (d. Wǔdé 武德 5 = 622; CBDB id 181749), native of Chénjùn 陳郡 Yángxià 陽夏, was a scholar-official of the Chén, Suí, and early Táng. Of the Yángxià Yuán lineage — one of the great southern aristocratic houses — he was the eldest son of Yuán Sīgōng 袁思恭. Under the Suí he served as Yībù shìláng 儀部侍郎; entering the Táng under Gāozǔ he was made Pīshū chéng 秘書丞 and was one of the four named compilers of the Yìwén lèijù 藝文類聚 (KR3k0003), the project for which he is principally remembered in catalog literature. He died before the completion of the Yìwén lèijù in 624. His biography survives in fragmentary form in the Xīn Táng shū · Yìwén zhì and is summarised in the introductory matter to Wāng Shàoyíng’s 1965 critical edition of the Yìwén lèijù.
