Emperor Qianshao of Han (, died 184 BC), personal name said to be Liu Gong , was the third emperor of the Han Dynasty in China. He was a son, likely the oldest son, of Emperor Hui, likely by a concubine -- although there is some controversy on the subject—and adopted by Emperor Hui's wife, Empress Zhang Yan. At the instigation of his grandmother, Empress Dowager Lü, Empress Zhang had Emperor Qianshao's mother put to death.
