Li Shidao (Chinese: 李師道) (died March 8, 819) was a general of the Chinese dynasty Tang Dynasty, who, as the successor to his brother Li Shigu, ruled Pinglu Circuit (平盧, headquartered in modern Tai'an, Shandong) in a de facto independent manner from the imperial government. In 818, after he reneged on an offer to submit three of Pinglu's 12 prefectures to imperial control, Emperor Xianzong declared a campaign against him. In 819, his officer Liu Wu turned against him and killed him, submitting to imperial authority.
