Duke Huan of Chen (Chinese: 陳桓公; pinyin: Chén Huán Gōng; reigned 744 BC – died 707 BC), personal name Gui Bao, was a duke of the Chen state.
After a reign of 38 years, he died in 707 BC under strange circumstances.
The uncertainty of Duke Huan's death threw the state into turmoil, and his younger brother Chen Tuo took the opportunity to murder Duke Huan's son Crown Prince Mian and usurp the throne.
[2][1] Before his death, Duke Huan had married a princess of the neighbouring state of Cai, who gave birth to a son named Yue.
Dai Gui was the mother of Duke Huan of Wey.
