Xiāngōng 先公 — literally “the Former Gentleman” or “Elder Sir” — is a translator known only by this designation, attested in the Chū sānzàng jì jí (T2145) and subsequent canonical bibliographies as the translator of two short single-fascicle excerpts from the Samādhirāja-sūtra: KR6i0277 Fó-shuō yuèdēng sānmèi jīng (T640) and KR6i0278 Fó-shuō yuèdēng sānmèi jīng (T641). The catalogs class him in the Liú-Sòng era (420–479), but no other biographical information has been recovered. Some later bibliographical attempts at identification (e.g. with Xiān-gōng-zhú 先公竺) are speculative and not accepted in modern scholarship. Both of his surviving translations are partial Chinese versions of the same Indic Samādhirāja underlying the much fuller T639 (Narendrayaśas, Northern Qí 557–559).
