汉献帝
Zhang Yang () (died 198), courtesy name Zhishu, was an official and minor warlord who lived during the late Eastern Han dynasty of China. Originally from Yunzhong Commandery (雲中郡; northern Shanxi) in the north, he eventually became the "de facto" ruler of Henei Commandery (河內郡; northern Henan). Although threatened by powerful warlords such as Cao Cao and Yuan Shao, Zhang Yang still provided refuge for Emperor Xian of Han numerous times, eventually attaining the rank of Grand Marshal (大司馬).
