Hassan ibn Atahiyah (Arabic: حسان بن عتاهية) (died 750) was a governor of Egypt for the Umayyad Caliphate for a portion of 745.
Arriving in the province in March, he initially attempted to disband the army units that had been raised by Hafs, but this measure was violently rejected by the soldiers and a mutiny quickly broke out.
The soldiers declared that they would refuse to recognize any governor other than Hafs and placed Hassan under siege in his house, while others proceeded to the Mosque of Fustat and called for Marwan to be deposed from the caliphate.
[4] According to al-Kindi, he later returned to Egypt and was appointed as sahib al-shurtah after Hafs and his supporters were purged by Hawtharah ibn Suhayl;[5] Ibn Taghribirdi on the other hand claims that he remained at the Umayyad court until the time of the Abbasid Revolution.
[1] In any case, he fell victim to the revolution following the fall of the Umayyad house in 750; brought before the new governor Salih ibn Ali, he was flogged and subsequently turned over for execution.
