Emperor Cheng of Han (51–7 BC) was an emperor of the Chinese Han Dynasty ruling from 33 until 7 BC. Under Emperor Cheng, the Han dynasty continued its slide into disintegration while the Wang clan continued its slow grip on power and on governmental affairs as promoted by the previous emperor. Corruptions and greedy officials continued to plague the government and as a result rebellions broke out throughout the country. Emperor Cheng died after a reign of 26 years and was succeeded by his nephew.
