Empress Xu (?皇后) (personal name unknown) (died 8 BC) was an empress during Han Dynasty, who came from a powerful family and who was initially very much loved by her husband Emperor Cheng, but who eventually lost favor and, as a result of the machinations of her eventual successor, Empress Zhao Feiyan, was deposed. After she was removed, she tried in vain to regain a measure of dignity by conspiring with her husband's cousin Chunyu Zhang (淳于?), but that conspiracy would eventually lead to her being forced to commit suicide.
