Ibrahim Hassan Tali al-Asiri (Arabic: ابراهيم حسن طالي العسيري; April 18 or 19, 1982 – 2017) was a citizen of Saudi Arabia suspected of being chief bomb-maker of al-Qaeda in the Arabian Peninsula.

On August 27, 2009, Abdullah blew himself up at the Jeddah palace of Saudi Arabia's Deputy Minister of the Interior prince Mohammed bin Nayef, in attempt to assassinate him after posing as a repentant militant.
