Sidi Mohammed ibn Nasir (مْحَمَّد بنَّاصر) or Mohammed ibn Mohammed ibn Ahmed ibn Mohammed ibn al-Hussayn ibn Nasir ibn Amr abu Bakr al-Drawi al-Aghlabi (1603–1674) was a Moroccan Sufi and founder of the Nasiriyya zawiyya of Tamegroute. Sidi Muhammad bin Nasir was a theologian, scholar and physician, especially interested in mental disorders. He wrote several works of fikh, some poetry, and hundreds of letters and treatises on Islamic law. He followed and extended the teachings of Shadhili and under his leadership the Nasiriyya became the "mother zawiya" of Sufism in the Maghreb with several branches in different parts of the country, including the zawiya of Irazan in the Sous valley where 500 students were financed by the brotherhood. The scholar Al-Yusi was one of his students and praised him in a well-known poem.
