Abu al-Hasan Ali ibn Muhammad al-Samarri (Arabic: أَبُو ٱلْحَسَن عَلِيّ ٱبْن مُحَمَّد ٱلسَّمَّرِيّ, ʾAbū al-Ḥasan ʿAlīy ibn Muḥammad as-Sammarīy) was the last of the Four Deputies, who are believed by the Twelvers to have successively represented their Hidden Imam, Muhammad al-Mahdi, during his Minor Occultation (874–941 CE). Al-Samarri in this role succeeded Abu al-Qasim al-Husayn ibn Ruh al-Nawbakhti in 937.

Al-Samarri is said to have received a letter from Muhammad al-Mahdi shortly before his death in 941 CE. The letter predicted the death of al-Samarri in six days and announced the beginning of the complete occultation, later called the Major Occultation, which continues to this day. The letter, ascribed to Muhammad al-Mahdi, added that the complete occultation would continue until God granted him permission to manifest himself again in a time when the earth would be filled with tyranny.
