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). However, his father moved to Jiankang (建康), where he was born. His secular name was Yu. As a young boy he practiced devotions at Jianchu Monastery. At 14, rather than acquiesce to an arranged marriage, he took novice vows and entered Dinglin Monastery, Zhongshan in Jiankang. He was ordained as a bhikkhu aged 20 and received instruction in Vinaya by Faying (d.480). He became renown as a master of the Vinaya.[1]
