Tuor is the father of the Elvish hero Eärendil in J.R.R. Tolkien’s legendarium.
Tuor is a Man of the House of Hador and a central figure in the First Age. He was chosen by the Vala Ulmo to carry a warning to the hidden city of Gondolin. There he married Idril Celebrindal, the daughter of Turgon, King of Gondolin. Their son was Eärendil.
Eärendil’s ancestry is unusually important because he was descended from both Men and Elves. He later sailed to Valinor carrying a Silmaril and pleaded for aid against Morgoth. His voyage led to the intervention of the Valar, and he became the mariner whose star was seen in the night sky.
Tuor is sometimes confused with Beren because both are heroic Men connected to Elves. Beren, however, married Lúthien and was the father of Dior. Tuor’s marriage to Idril belongs to a separate First Age story centered on Gondolin.
