Song Shenxi (Chinese: 宋申錫) (died August 18, 833), courtesy name Qingchen (慶臣), was an official of the Chinese dynasty Tang Dynasty, serving briefly as a chancellor during the reign of Emperor Wenzong. He was most known for planning with Emperor Wenzong to eliminate the power of the eunuchs from the court but then being falsely implicated in a plot to overthrow Emperor Wenzong and replace the emperor with Emperor Wenzong's brother Li Cou the Prince of Zhang. As a result, Song was exiled and died in exile.
