Biography
Lindir was a listener at one of Bilbo's poetry readings at Rivendell, his name implying (see Etymology below) he may have been a minstrel. After Bilbo finished reciting the Song of Eärendil, Lindir said he could not tell which parts Aragorn wrote and what parts were written by Bilbo, because all mortals seem alike to Elves.

Portrayal in Adaptations
In The Hobbit: An Unexpected Journey he is played by actor Bret McKenzie. In the film he appears as Elrond's right hand. He is also seen greeting Thorin and Company when they arrive in Rivendell.
