Fëanor is a fictional character in J. R. R. Tolkien's The Silmarillion. He creates the Tengwar script, the palantír seeing-stones, and the three Silmarils, the skilfully-forged jewels that give the book their name and theme, triggering division and destruction. He is the eldest son of Finwë, the King of the Noldor Elves, and his first wife Míriel.

The Silmarils are three fictional brilliant jewels in J. R. R. Tolkien's legendarium, made by the Elf Fëanor, capturing the unmarred light of the Two Trees of Valinor. The Silmarils play a central role in Tolkien's book The Silmarillion, which tells of the creation of Eä and the beginning of Elves, Dwarves and Men.
