Shang Yang (ca. 390-338 BC) was a Chinese statesman and political philosopher. He was one of the founders of Chinese Legalism and organized the rise to power of the Ch'in dynasty.

The real name of Shang Yang was Kung-sun Yang; he was also known as Wei Yang. He was born in Wei, a state in north-central China. His mother was a concubine of a member of the Wei royal family. In his youth he specialized in criminal law and served as tutor to the Wei princes. He was a favorite of the Wei prime minister, who recommended to the Wei ruler that Shang Yang succeed to the ministry upon his death. This request was denied, and Shang Yang, feeling that he was not appreciated in Wei, journeyed to the western state of Ch'in, which had been seeking men who could offer practical advice on state affairs.
