Ori is a Fictional character in J. R. R. Tolkien's Fictional universe of Middle-earth. Ori is a Dwarf of the House of Durin, and brother to Nori and Dori.
In The Hobbit, Ori (and his brothers) accompanied their lord Thorin Oakenshield on the Quest of Erebor, in which they were assisted by the Hobbit Bilbo Baggins.
Spoiler warning: Plot and/or ending details follow.
Years later Ori travelled with Balin and a force of Dwarves on a fatal attempt to reclaim their ancient mansions of Khazad-dûm which were already occupied by the Goblins. Ori and the remaining Dwarves perished during a final stand inside the Chamber of Mazarbul. On the Quest of Mount Doom, the Fellowship of the Ring journeyed through Moria and discovered the book that contained the records of the expedition written by Ori.
