Qi Wannian (died 299), or Qiwannian, was an ethnic Di chieftain and rebel leader during the Western Jin dynasty of China. In 296, he became leader of a tribal uprising against Jin in Qinzhou and Yongzhou that lasted until 299. Although it was put down in the end, the uprising raised some concerns among ministers regarding the tension between the Han and tribal people while also triggering a mass migration of northerners to the south that continued into the 4th century as northern China fell into civil war and rebellions.
