Huan Wen's Northern Expeditions were a series of expeditions launched by the Jin Dynasty (266–420) general Huan Wen and aimed at attempting to reclaim Jin's territory north of the Huai River. After a series of failed expeditions by his rival Yin Hao, Huan Wen was placed in charge of his position. The Jin court held the expeditions to capitalize on a disunified north following the destruction of Former Zhao in 351. For Huan Wen, however, he was looking to distinguish himself well enough to receive the nine bestowments and take over the throne. Due to the lack of support from the Jin court, the expeditions were unsuccessful in the end, only serving as a stepping stone for Former Qin's unification of the north.
