Huan Wen (312–373), courtesy name Yuanzi, formally Duke Xuanwu of Nan Commandery, is a general of the Jin Dynasty (265-420).

He is commonly viewed as one of the greatest generals since Jin's loss of northern China, as he leads the campaign that destroys Cheng Han and annexes its lands to Jin, and has some successes against the northern states Former Qin and Former Yan (although both campaigns ultimately end in failure, perhaps due to his overcautiousness).

After his death, the Huan clan is entrenched in the Jin power structure for decades.

After his son Huan Xuan temporarily usurps the Jin throne in 403 as the emperor of Chu, he is posthumously honored as Emperor Xuanwu of Chu with the temple name of Taizu.
