A dwarf of Durin’s Folk, b. TA 2859, d. TA 2941. He was the elder son of Dís, sister of Thorin Oakenshield.

In The Hobbit, Fíli and his younger brother Kíli, accompanied Thorin to the Lonely Mountain in TA 2941. At Bilbo's Unexpected Party he was recorded as having a yellow beard, a blue hood and a silver belt. He played the fiddle well, and was skilled in the making of fires.

With his brother it was Fili who found the cave where the company was captured by goblins (orcs), and being young and sharp-eyed it was Fili who threw the rope to hook the boat at the Enchanted River in Mirkwood.

Fili had a longer nose than Kili and Bilbo recognised it sticking through the threads when the dwarves were captured by the Mirkwood Spiders. Fili helped free the others, but had lost a good deal of his beard as Bilbo cut him free.

Fili was young, upbeat and helpful. He coped better than most with hiding in a barrel. With Kili, Balin and Bilbo he reconnoitred the Front Gate of the Lonely Mountain and with Kili went to retrieve the surviving ponies and supplies after the disappearance of Smaug.

Fili and Kili fought with honour in the Battle of Five Armies, and fell there defending Thorin.
