Duke Chu of Jin (simplified Chinese: 晋出公; traditional Chinese: 晉出公; pinyin: Jìn Chū Gōng) was from 474 to 452 BC the ruler of the State of Jin, a major power during the Spring and Autumn period of ancient China. His ancestral name was Ji, given name Zao, and Duke Chu was his posthumous title. He succeeded his father, Duke Ding of Jin, who died in 475 BC. He was in effect the last ruler of Jin, as at the end of his reign Jin would be partitioned into the new states of Han, Zhao, and Wei, although the title of the Duke of Jin would still exist in name only for several more generations.
