Liu Yun, Chinese governor (jiedushi)
Liu Yun (died February 24, 951), probably known as Liu Chengyun before 949, referred to in historical sources as the Duke of Xiangyin (湘陰公), was a military governor of the Later Han dynasty during the Five Dynasties period. He was an ethnic Shatuo.

A cousin of the Later Han emperor Liu Chengyou, Liu Yun was named Liu Chengyou's successor by Empress Dowager Li following Liu Chengyou's death, but on his way to the capital he was put under house arrest and later executed on orders of Guo Wei, who had founded the Later Zhou dynasty. After his death, his father Liu Chong founded the Northern Han dynasty and waged a war against Later Zhou to avenge his son's death.
