Duke Wen of Chen ({{zh|t=陳文公|p=Chén Wén Gōng}}; reigned 754 BC – died 745 BC), personal name Gui Yu, was a monarch of the Chen state.{{sfn|Han|2010|pp=2778–80}}

Duke Wen succeeded his father Duke Ping, who died in 755 BC. He reigned for 10 years and died in 745 BC. He was succeeded by his son, Bao (Duke Huan). When Duke Huan died in 707 BC, his younger brother Chen Tuo murdered Crown Prince Mian and usurped the throne of Chen. Chen Tuo was then killed by the army of the neighbouring Cai state, which restored the throne to Duke Huan's younger son, Yue (Duke Li).{{sfn|Han|2010|pp=2780–1}}

Duke Zhuang I of Wey (衛前莊公) married two princesses of Chen, Li Gui (厲媯) and her younger sister Dai Gui (戴媯), who were likely daughters of Duke Wen of Chen. Dai Gui was the mother of Duke Huan of Wey (衛桓公).{{sfn|Yang|2009|p=31}}
