Sengyou (Chinese: 僧祐; pinyin: Sēngyòu; 445–518 AD) was a Buddhist monk and early medieval Chinese bibliographer and noted chiefly for being the author of Collected Records Concerning the Tripitaka (出三藏記集 Chu sanzang ji ji, T 2145), which includes a catalogue of Buddhist texts translated into Chinese, and the Collection on the Propagation and Clarification of Buddhism (弘明集 Hong Ming Ji, T 2102) Sengyou's ancestral home was Xiapi in Pengcheng Commandery (northwest of modern Suining, Jiangsu).
