Li Wei (simplified Chinese: 李卫; traditional Chinese: 李衛; pinyin: Lǐ Wèi; Styled Youjie (又玠), posthumous name Minda (敏達); February 2, 1687 – December 3, 1738) was a Qing dynasty mandarin who lived during the reign of the Yongzheng Emperor (1722–1735).
He served the Yongzheng emperor, helped implement his reforms, and held various regional governing positions.
In 1729, in a swift act, Li Wei helped crush Ming Dynasty-loyalists present in the Nanjing area.
In 1732, he was appointed the Viceroy of Zhili, overseeing the area immediately outside of Beijing (somewhat analogous to present-day Hebei).
In September 1738, while visiting Qinling tombs with the Qianlong Emperor, Li Wei fell ill with a lung infection, and died at the age of 52.
