Liu Can (柳璨; died January 27, 906[1][2]), courtesy name Zhaozhi (炤之[3] or 昭之[4]), formally the Baron of Hedong (河東男), nicknamed Liu Qiezi (柳篋子, "Liu the File Folder"), was an official of the Chinese Tang dynasty, serving as a chancellor during the reigns of Emperor Zhaozong and Emperor Zhaozong's son Emperor Ai, near the end of the dynasty.
He was an associate of warlord Zhu Quanzhong, the military governor (jiedushi) of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan). He assisted Zhu in the process of usurping the Li family to seize the Tang throne. However, eventually, Zhu became impatient of the pace that Liu and his other associates Jiang Xuanhui (蔣玄暉) and Zhang Tingfan (張廷範) were taking in that process and became suspicious that they had turned against him. Zhu then executed Liu Can and all his associates.
