Li Shen (李紳) (died July 29, 846), courtesy name Gongchui (公垂), formally Duke Wensu of Zhao (趙文肅公), was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Wuzong.
It is not known when Li Shen was born. His family claimed ancestry from the southern branch of the prominent Li clan of Zhao Commandery (趙郡, roughly modern Shijiazhuang, Hebei), but was only able to trace its ancestry back to the Northern Wei official Li Shanquan (李善權) and Li Shanquan's descendants who served as officials of Northern Wei and Sui Dynasty. Li Shen's great-grandfather Li Jingxuan served as a chancellor during the reign of Emperor Gaozing, and his great-granduncle Li Yuansu served as a chancellor during the reign of Emperor Gaozong's wife Wu Zetian. Both Li Shen's grandfather Li Shouyi (李守一) and father Li Wu (李晤) served as county magistrates. In Li Wu's case, he served three times at Jintan (金壇, in modern Changzhou, Jiangsu), Wucheng (烏程, in modern Huzhou, Jiangsu), and Jinling (晉陵, in modern Changzhou as well). He therefore settled his family in the region, at Wuxi.
Li Shen was five-years-old when Li Wu died, and he therefore was raised by his mother Lady Lu, who taught him the Confucian classics. It was said that Li Shen was short in stature but energetic, and was capable in songs and poetry. The year that he submitted himself to the local preliminary round of the imperial examinations, his poems became well known in the region.
