Ahmad ibn Ibrahim ibn Ali ibn Munim al-Abdari (; died 1228), often referred to as ibn Munim, was a mathematician, originally from Dénia in Andalusia. He lived and taught in Marrakesh where he was known as one of the best scholars in geometry and number theory.Helaine Selin, Encyclopaedia of the history of science, technology, and medicine in non-western cultures, p. 427 (retrieved 28-8-2010). See in particular the section "Combinatorics in the Maghreb: Ibn Mun'im", pp. 94–99. He is often confused with Muhammad ibn 'Abd al Mun'im, a different mathematician who worked in the court of Roger II of Sicily.
