Empress Helian (赫連皇后) (died 453), formally Empress Taiwu (太武皇后), was an empress of the Xianbei-led Chinese Northern Wei dynasty. Her husband was Emperor Taiwu. She was a daughter of the Hu Xia's founding emperor Helian Bobo (Emperor Wulie). In 428, during the reign of her brother Helian Chang, Emperor Taiwu led his Northern Wei forces to capture the Xia capital Tongwan (統萬, in modern Yulin, Shaanxi), and while Helian Chang fled, she was captured along with most nobles and officials of Xia. She and her two sisters were all taken as Emperor Taiwu's imperial consorts. In 432, she was created empress, presumably after being able to pass the traditional Tuoba tribe test by being able to forge a gold statue.
