What is Gandalf's name in Sindarin (Elvish)?

Gandalf's name in Sindarin (Elvish) is Mithrandir. The name means “Grey Pilgrim” or “Grey Wanderer,” matching Gandalf’s role as a travelling wizard and his best-known identity as Gandalf the Grey.

Tolkien gives Gandalf several names in different languages and cultures. The Elves call him Mithrandir, while the Dwarves know him as Tharkûn, a name associated with a staff or staff-bearer. In the West, before becoming an Istari wizard, he was known as Olórin.

The name remains Mithrandir even after Gandalf returns as Gandalf the White. That transformation changes his rank, clothing, and symbolic role, but it does not replace his Elvish name. A common mix-up is confusing Mithrandir with Gandalf’s original Maiar name, Olórin, or with Tharkûn, his Dwarvish name.
