Li Wei (February 2, 1688 – December 3, 1738), courtesy name Youjie, known by the pseudonym Qia Ting, was a native of Tongshan in Jiangnan (now Lizhai Village, Dashahe Town, Feng County, Xuzhou, Jiangsu Province) and a prominent official during the Qing Dynasty.

In the 56th year of the Kangxi reign (1717), Li Wei donated funds to secure the position of Yuanwailang, after which he entered imperial service and served through the reigns of Emperors Kangxi, Yongzheng, and Qianlong. Deeply admired by Emperor Yongzheng, Li Wei held a succession of high-ranking posts, including Langzhong of the Ministry of Revenue, Yundian Dao of Yunnan overseeing salt administration, Buzhengshi, Governor of Zhejiang, Governor-General of Zhejiang, Minister of War, Acting Minister of Justice, and finally Governor-General of Zhili. Known for his integrity and courage in the face of powerful officials, Li Wei was always attuned to the hardships faced by ordinary people during his tenure, earning him widespread respect and affection among the populace. He passed away in the 3rd year of the Qianlong reign (1738), prompting Emperor Qianlong to order a ceremonial burial befitting a governor-general and posthumously bestow upon him the honorary title "Min Da."
