A vizier is a high-ranking advisor to a monarchy in Eastern cultures. The Doctor has encountered several viziers, both on and off Earth.

• The Sclaponian Grand Vizier (PDA: Island of Death)
• The glass Vizier of Fortalice (EDA: The Scarlet Empress)

Bernice Summerfield also encountered an indiviual who called himself the Vizier, whilst on Perfecton. (BNA: Oh No IT Isn't!)
