The Fellowship of the Ring in J.R.R. Tolkien’s The Lord of the Rings had nine members.
The company consisted of Frodo Baggins, Samwise Gamgee, Merry Brandybuck, Pippin Took, Aragorn, Boromir, Legolas, Gimli, and Gandalf. They were formed at Rivendell to help carry the One Ring toward Mordor and ultimately destroy it in Mount Doom.
The number nine deliberately contrasts with the nine Ringwraiths, or Nazgûl, who pursue the Ring-bearer. Gandalf leads the company at first, but the Fellowship later breaks apart after events at Amon Hen. Its members then continue the struggle in separate groups and journeys.
A common mix-up is counting Bilbo, Elrond, or other Rivendell residents among the Fellowship. They assist the quest but are not part of the formal nine-member company. Tolkien’s use of a small, varied group also lets the story combine different peoples and cultures of Middle-earth.
