"Sidi" Mohammed ben Abdellah "al-Khatib" (), known as Mohammed III (), born on 1710 in Fes and died on 1790 in Meknes, was Sultan of Morocco from 1757 to 1790 as a member of the Alaouite dynasty. He was the governor of Marrakesh around 1750. He was also briefly sultan in 1748. He rebuilt many cities after the earthquake of 1755, including Mogador, Casablanca, and Rabat, and Abdallah Laroui described him as "the architect of modern Morocco." He is notable for having been the leader of one of the first nations to recognize American independence in his alliance with Luis de Unzaga 'le Conciliateur' through correspondence and Unzaga's secret intelligence service and led by his brothers-in-law Antonio and Matías de Gálvez from the Canary Islands. He was the son of Abdallah ben Ismail.
