Xiao Baojuan (蕭寶卷) (483–501), né Xiao Mingxian (蕭明賢), commonly known by his posthumously demoted title of Marquess of Donghun (東昏侯), courtesy name Zhizang (智藏), was an emperor of the Chinese dynasty Southern Qi. He was known as a violent ruler who executed high-level officials at his whim, and this drew several major rebellions, the last of which, by his general Xiao Yan, overthrew him and eventually his dynasty, with Xiao Yan establishing Liang Dynasty. He is known as the Marquess of Donghun because Xiao Yan demoted him to that title after he was killed in a siege of the capital Jiankang.
