Tarcil is a fictional character in J. R. R. Tolkiens universe of Middle-earth.
He ascended the throne of Arnor in 435 T.A. on the death of his father Eldacar, he was the great-grandson of Isildur.
His reign was without any event and he died in 515 T.A. and was succeeded by his son Tarondor.
The name Tarcil (also spelt Tarkil) also appears in the History of the Lord of the Rings as another nickname for Aragorn: its meaning is apparently "High Man", a synonym for Dúnadan. The Orcish term "tark" for a Dúnadan is without doubt derived from this.
