Abū al-Abbas Ahmad ibn Muhammad ibn Idhāri al-Marrākushi (Arabic: أبو العباس أحمد ابن عذاري المراكشي) who lived in the late 13th and the early 14th century, was the author of an important medieval text (Al-Bayan al-Mughrib) on the history of the Maghreb and Iberia written in 1312.
Little is known about the life of this author, who was born in and lived in Marrakech. His history of the Maghreb and Iberia is widely regarded among modern researchers as containing valuable information not found elsewhere, including extracts from older works now lost.
