Duke Qing of Jin (simplified Chinese: 晋顷公; traditional Chinese: 晉頃公; pinyin: Jìn Qǐng Gōng, died 512 BC) was the ruler of the State of Jin from 525 to 512 BC, a major power during the Spring and Autumn period of ancient China. His ancestral name was Ji, given name Quji, and Duke Qing was his posthumous title. He succeeded his father, Duke Zhao of Jin, who died in 526 BC. In 514 BC two smaller clans – Qi (祁) and Yangshe (羊舌) – were exterminated and the six major clans grew even more powerful. Duke Qing reigned for 14 years and died in 512 BC. He was succeeded by his son, Duke Ding of Jin.
