Péi Xuán 裴玄 (fl. mid 3rd century), zì Yànhuáng 彥黃, was a SūnWú 孫吳 official from Pèiguó 沛國 (modern Ānhuī). He is described in Sānguó zhì commentary as the father of Péi Jùn 裴儁 and is mentioned in scattered notices in Sānguó zhì·Wúshū. He served under Sūn Quán 孫權. His birth and death years are not preserved; he is conventionally placed in the mid 3rd century. CBDB has no entry. Sòng catalogs sometimes write the name as 裴元, observing the yuán 玄→元 taboo of the Sòng emperor Shènzōng 神宗.
In the Kanripo corpus he is the attributed author of KR3a0147 Péi Shǐ xīnyán 裴氏新言.
