In J.R.R. Tolkien’s mythology, Gandalf’s original name is Olórin.
Olórin is Gandalf’s name in Valinor, before he travels to Middle-earth as one of the Istari. The Istari are Maiar, powerful spiritual beings sent in embodied form to help the peoples of Middle-earth resist Sauron. In the West, Olórin is associated with wisdom, pity, and the healing of others.
Tolkien presents Gandalf under different names in different cultures. The name Gandalf is used by the Men of the North, while the Elves call him Mithrandir, meaning “Grey Pilgrim.” He is also known as Tharkûn among the Dwarves. These names identify the same character rather than separate wizards.
Olórin should not be confused with Curumo, the original name of Saruman, or Mairon, the original name of Sauron. All three are Maiar, but they take radically different paths. Gandalf remains committed to resisting domination and encouraging others to choose courage for themselves.
