Zhāng Chéngxiān 張承先 was a Táng-dynasty Daoist master and liturgical editor. He is attested in DZ 508 Wúshàng huánglù dàzhāi lìchéng yí 無上黃籙大齋立成儀 20.9b–11b, and is the editor of DZ 411 Tàishàng dòngxuán língbǎo wǔdì jiàojì zhāozhēn yùjué KR5b0095 — a stand-alone Five-Emperors offering-rite extracted by him from DZ 352 Chìshū yùjué miàojīng 2.20a–28b. His editorial note at the close of DZ 411 states his purpose in excerpting the ritual — “that it might serve for an independent ceremony.” No other biographical details are recorded; no CBDB record.
