Thumal the Qahraman (Arabic: ثمل القهرمانة) (died 929) was a Muslim woman appointed in 918 as a judge in a maẓālim (secular administrative) court during the reign of Caliph al-Muqtadir (r. 908–932). She was not a Qadi (a judge adjudicating Islamic law), for she only dealt with secular law. She was put in charge of rescripting the petitions which petitioners brought to the court. Her position was an extraordinary unique for her sex. She was appointed by Umm Jafar Muqtadir, the mother to caliph Jafar al-Muqtadir-billah (r. 908–923), the eighteenth Abbasid caliph.
