Ulpia Severina (fl. 3rd century) was a Roman Empress, the wife of the emperor Aurelian. There is evidence that she reigned in her own right for some period after Aurelian's death in 275, which would make her the only woman to have ruled over the entire Roman Empire by her own power. Very little is known about her, as there are no literary sources mentioning her existence. Almost everything known about her, including her name, is gathered from coins and inscriptions.
