Nayef bin Abdulaziz Al Saud was the crown prince of Saudi Arabia and deputy prime minister from October 2011 and the minister of interior from October 1975 until his death in June 2012.

The crown prince of Saudi Arabia is the second-most important position in Saudi Arabia, second to the King, and is his designated successor. Currently, the Crown Prince assumes power with the approval of the Allegiance Council after he is nominated by the King. This system was introduced to the country during the reign of King Abdullah. In the absence of the King, an order is issued to have the Crown Prince manage the affairs of the state until the King's return.
