Muhammad Hamid Abu al-Nasr (ar:محمد حامد أبو النصر) was the fourth General Guide (Murshid al-'am) of the Egyptian Muslim Brotherhood. A controversial choice to lead the group after the 1986 death of longtime General Guide 'Umar al-Tilmisani, al-Nasr was opposed by a large faction backing other candidates such as Salah Shadi or Husayn Kamal al-Din, but was installed as Murshid by Mustafa Mashhur, who succeeded him soon after.
