Xu Zhixun (徐知訓) (895-918) was the oldest biological son of Xu Wen, the regent of the Chinese Five Dynasties and Ten Kingdoms period state Wu. He served as the junior regent from 915 to his death in 918, with his father stationing himself at Jinling away from the capital Guangling (廣陵, in modern Yangzhou, Jiangsu). Xu Zhixun's arrogance alienated the Wu generals, and, in 918, after he angered the general Zhu Jin, Zhu assassinated him.
