Abu Abd Allah Muhammad al-Idrisi al-Qurtubi al-Hasani al-Sabti or simply Al Idrisi (Arabic: 堧堥? 媢堥堹 塈??? ?堶?堹 塈?堨堹堭?堻??? Latin: Dreses) (1099??165 or 1166) was a Moroccan Muslim geographer, cartographer, Egyptologist and traveller who lived in Sicily, at the court of King Roger II. Muhammed al-Idrisi was born in Ceuta then belonging to the Almoravid Empire and died in Sicily. Al Idrisi was a descendent of the Idrisids, who in turn were descendants of Hasan bin Ali, the son of Ali and the grandson of the Islamic prophet Muhammad.

Al-Idrisi traced his descent through a long line of Princes, Caliphs and Sufi leaders, to The Prophet Muhammad. His immediate forebears, the Hammudids (1016??058), were an offshoot of the Idrisids (789-985).

Al-Idrisi's was born in Ceuta, where his great-grandfather had fled after the fall of M獺laga in Al-Andalus (1057). He spent much of his early life travelling through North Africa, and Spain and seems to have acquired detailed information on both regions. He visited Anatolia when he was barely 16. He is known to have studied in C籀rdoba, and later taught in Constantine, Algeria.

Apparently his travels took him to many parts of Europe including Portugal, the Pyrenees, the French Atlantic coast, Hungary, and J籀rv穩k also known as York, in England.
