The Saudi Arabian National Guard (SANG) (Arabic: الحَرَس الوَطنيّ, romanized: al-Ḥaras al-Waṭanī), also known as the White Army, is one of the three major branches of the military forces of the Kingdom of Saudi Arabia.

The national guard is under the administrative control of the Ministry of National Guard, instead of the Ministry of Defence. It differs from the regular Saudi Arabian Army in being forged out of tribal elements loyal to the House of Saud and tasked with protecting the royal family from internal dangers such as a coup d'état.
