Abu al-Abbas Ahmad al-Darjini () was an Ibadi Muslim scholar. He is mostly known for his book Kitab Tabaqat al-Mashayikh bil-Maghrib.
His full name Abu al-âÂÂAbbas Ahmad ibn SaâÂÂid ibn Sulayman ibn âÂÂAli ibn Yakhlaff al-Mazati al-Darjini. He was born and educated in the al-Jerid region, in what is now Tunisia, hailing from a family with deep roots in the area.
His principal work is Kitab Tabaqat al-Mashayikh, also known by its later title Kitab Tabaqat al-Mashayikh bil-Maghrib. The term Maghrib was added by modern editors to reflect the book's primary focus on the Ibadi community in North Africa. Much of the work is based on, and directly drawn from, the earlier Kitab Siyar al-Aimmah wa Akhbaruhum by Abu Zakariyya al-Warjlani.
