Han Jian (韓建) (855[1]-August 15, 912[2][3]), courtesy name Zuoshi (佐時), was a warlord late in the Chinese Tang dynasty, who eventually became a subject of the succeeding Later Liang state. He is most well known for having had Emperor Zhaozong of Tang under his control at his power base at Hua Prefecture (華州, in modern Weinan, Shaanxi) from 896 to 898 and slaughtering the imperial princes while Emperor Zhaozong was there.
