Barahir was one of the Dúnedain of Gondor, and the grandson of Faramir.

It was Barahir who wrote "The Tale of Aragorn and Arwen", which appears in Appendix A of The Lord of the Rings.

He was most likely Prince of Ithilien and Steward of Gondor. It is stated in some resources that Barahir's father's name was Elboron.
