Xiàng Jùn 項峻 (life-dates unknown, fl. mid–3rd century), an official of Sānguó Wú 三國吳 under Sūn Quán 孫權 and Sūn Liàng 孫亮. He served as lángzhōng 郎中 and was, together with the Grand Astrologer (tàishǐlìng) Dīng Fú 丁孚, commissioned in the later Wú reign to compile an official Wúshū 吳書. The draft proved historiographically deficient and was rejected by reviewers Xuē Yíng 薛瑩 and Huá Hé 華覈, who reassigned the project to Wéi Zhāo 韋曜 and others. Xiàng’s surviving work is the Shǐxué piān 始學篇 KR3j0196 — one of the earliest documented Chinese lèishū (encyclopedic primers) — long lost and known only through citations in Chūxué jì 初學記, Tàipíng yùlǎn 太平御覽, Běitáng shūchāo 北堂書鈔, and the NánQí shū yúfú zhì 南齊書·輿服志; the work was reconstructed in the Qīng by Mǎ Guóhàn 馬國翰 in his Yùhán shānfáng jíyì shū 玉函山房輯佚書. He is not recorded in CBDB.
