Chen Xianqi (Chinese: 陳仙奇) (died c.August 786[1]) was a general of the Chinese Tang dynasty. He had served under Li Xilie, who had rebelled against Emperor Dezong and claimed the title of emperor of his own state of Chu. Li Xilie, however, by 786, had become repeatedly defeated by Tang forces. When Li Xilie grew ill, Chen had him poisoned and then submitted to Tang, but was himself in turn assassinated by Wu Shaocheng later in the year.
