Su Jian (蘇檢) (died March 6, 903[1][2]), courtesy name Shengyong (聖用),[3] was an official of the Chinese Tang dynasty, who briefly served as chancellor from 902 to 903, while Emperor Zhaozong was under the physical control of the warlord Li Maozhen the military governor (Jiedushi) of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi) and Li's eunuch allies, led by Han Quanhui.
[4] In spring 902, apparently at Li Maozhen's recommendation, Wei Yifan was made chancellor, even though the commission came at Emperor Zhaozong's disgust.
The eunuchs initially wanted the imperial scholar Yao Ji to be made chancellor, but Yao declined the commission at the advice of his imperial scholar colleague Han Wo, who cited the likelihood of eventual retaliation by Zhu Quanzhong, the military governor of Xuanwu Circuit, who had by that point put Fengxiang Circuit's capital Fengxiang Municipality under siege to try to take the emperor from Li.
Soon thereafter, Su was made the deputy minister of public works (工部侍郎, Gongbu Shilang) and chancellor, with the designation Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事).
With food supplies running out and the residents of Fengxiang resorting to cannibalism, in 903, Li sued for peace, agreeing to surrender the emperor to Zhu.
