The Sash of the Three Orders is a decoration that combines the insignia of the Grand Crosses of the Military Orders of Christ, Aviz and St. James of the Sword. It is the symbol of the Portuguese presidential magistracy, in their capacity as the fount of the Portuguese honours system; therefore, it cannot be conferred on nationals or foreigners, nor can it be used outside the exercise of office of the President.

The Sash of the Two Orders was a Portuguese decoration that combined the Grand Crosses of the Military Orders of Christ and Aviz.
