Ziying, King of Qin (, died January 206  BC) was the third and last ruler of the Qin dynasty. He ruled over a fragmented Qin Empire for 46 days, from mid-October to early December 207  BC. He is referred to in some sources with the posthumous name Emperor Shang of Qin (秦殤帝) although Qin abolished the practice of posthumous names. (In Chinese tradition, even someone who never held a ruling title while he was alive might be given the posthumous title "emperor" after his death.)
