Ying Ziying, also known as Ziying, King of Qin (Chinese: 秦王子嬰; pinyin: Qín-wáng Zǐyīng, died c. January 206 BC), was the third and last ruler of the Qin dynasty of China. He ruled over a fragmented Qin Empire for 46 days, from mid-October to early December 207 BC. Unlike his predecessor, he ruled as a king instead of emperor. He is referred to in some sources with the posthumous name Emperor Shang of Qin (秦殤帝) although the Qin dynasty had abolished the tradition of according posthumous names to deceased monarchs.
