Tang Daoxi (唐道襲) (died August 21, 913) was an official and general of the Chinese Five Dynasties and Ten Kingdoms period state Former Shu. He was a close associate of Former Shu's founding emperor Wang Jian and held great power during Wang Jian's reign. This brought him into conflict with Wang Jian's son and crown prince Wang Yuanying. In 913, with both he and Wang Yuanying suspecting the other of being ready to launch a mutiny, their forces engaged in a battle at the Former Shu capital Chengdu. He was defeated by Wang Yuanying and killed in battle.
