Teng Xiu (died 288[1]), courtesy name Xianxian, was a military general of the state of Eastern Wu during the late Three Kingdoms period (220–280) of China.
During the reign of the fourth and last Wu emperor Sun Hao, Teng Xiu succeeded Xiong Mu (熊睦) as the Inspector (刺史) of Guang Province (廣州) and was known for being a capable governor.
He also promoted Teng Xiu to the rank of Governor (牧), gave him an additional appointment as General Who Guards the South (鎮南將軍), and granted him full authority and control over the military forces in Guang Province.
Teng Xiu then led troops from Guang Province to counter the invasion, but by the time he reached Baqiu (巴丘; present-day Yueyang, Hunan), Sun Hao had surrendered to the Jin dynasty, thus bringing an end to Eastern Wu's existence.
Later, he surrendered to the Jin dynasty as well, along with Lü Feng (閭豐; the Inspector of Guang Province) and Wang Yi (王毅; the Administrator of Cangwu Commandery).
