Liu Dan (simplified: 劉誕, traditional: 劉誕, pinyin: Liú Dàn) was Liu Yan’s second son. He and his elder brother Liu Fan and younger brother Liu Zhang remained at the capital with Emperor Xian while Liu Yan governed Yi Province. When Dong Zhuo controlled the court, he imprisoned Liu Fan, Liu Dan, and Liu Zhang at Meiwu (郿塢). Liu Yan later had Liu Zhang recalled to Yi Province on pretext of an edict, and kept him there. Liu Fan and Liu Dan remained in the north. When Liu Fan plotted with Ma Teng to attack Li Jue (李傕) at Chang’an, the plot was exposed; Liu Fan fled to Ma Teng and was killed in the fighting. Liu Dan was also killed—either in the same purge or when Dong Zhuo’s faction (Li Jue) executed the imprisoned brothers. The Hou Han shu and other sources record that Liu Fan and Liu Dan died in 194.
