Duke Xuan of Chen (Chinese: 陳宣公; pinyin: Chén Xuān Gōng; reigned 692 BC – died 648 BC), personal name Gui Chujiu, was a ruler of the Chen state.
However, it was his younger brother Lin (Duke Zhuang) who succeeded him, instead of his son Chen Wan (陳完).
However, in 672 BC, the 21st year of his reign, Duke Xuan's favourite concubine gave birth to a son named Kuan.
Duke Xuan killed Yukou and made Kuan his new heir apparent.
Afraid that his life was also in danger, Chen Wan fled to the State of Qi in the northeast.
