What is the name of the hidden waterfall where Frodo and Sam meet Faramir?

The hidden waterfall where Frodo and Sam meet Faramir is Henneth Annûn. The name means “Window of the Sunset” in Sindarin, one of Tolkien’s Elvish languages, and refers to a striking waterfall and cave in Ithilien.

Henneth Annûn was a concealed military refuge maintained by Gondor during its struggle against Mordor. Its hidden entrance lay behind the falling water, making the stronghold difficult for enemies to discover. Faramir and his Rangers used it as a base while patrolling Ithilien and attacking forces travelling between Mordor and occupied lands.

Frodo and Sam reached the site after being captured by Faramir’s men. Unlike Boromir, Faramir resisted the temptation to seize the One Ring, even after learning what it was. He questioned Frodo carefully and eventually allowed the hobbits to continue their journey, though he warned them about the dangers ahead.

The location is sometimes confused with Ithilien, which is the wider region, or Osgiliath, a ruined city nearby. Henneth Annûn is the specific waterfall refuge, while Faramir is the character who commands the Rangers there.
