Chen Jingxuan (陳敬瑄) (d. April 26, 893) was a general of the Tang dynasty of China, who came to control Xichuan Circuit (西川), headquartered in modern Chengdu, Sichuan by virtue of his being an older brother of the eunuch Tian Lingzi, who controlled the court of Emperor Xizong during most of Emperor Xizong's reign. Later, when Emperor Xizong's brother and successor Emperor Zhaozong tried to recall Chen, Chen refused, leading to a general campaign against him. He was eventually defeated and killed by Wang Jian, who took over his territory and later founded the Five Dynasties and Ten Kingdoms period state Former Shu.
It is not known when Chen Jingxuan was born. According to the Zizhi Tongjian, his family was from Xu Prefecture (許州, in modern Xuchang, Henan). He had at least two younger brothers, Chen Jingxun (陳敬珣) and one other who later became known as Tian Lingzi — as that younger brother became a eunuch in his young age and was adopted by a eunuch named Tian. He probably had two older brothers, as, at one point, Tian Lingzi referred to him as the third brother.
As of the start of the reign of Emperor Xizong (r. 873-888), Tian Lingzi became extremely powerful due to his close personal association with Emperor Xizong, such that Emperor Xizong even referred to him as "Father." Tian tried to intercede on Chen Jingxuan's behalf with Cui Anqian the military governor of Zhongwu Circuit (忠武, headquartered at Xu Prefecture) to have Chen made an officer under Cui, but Cui refused. Tian, therefore, had Chen come to the imperial capital Chang'an and made him an officer in the eunuch-commanded Left Shence Army (左神策軍), promoting him all the way to being a major general within a span of a few years.
