"The Council of Elrond" is the second chapter of Book 2 of J. R. R. Tolkien's bestselling fantasy work, The Lord of the Rings, which was published in 1954–1955. It is the longest chapter in that book at some 15,000 words, and critical for explaining the power and threat of the One Ring, for introducing the final members of the Fellowship of the Ring, and for defining the planned quest to destroy it. Contrary to the maxim "Show, don't tell", the chapter consists mainly of people talking; the action is, as in an earlier chapter "The Shadow of the Past", narrated, largely by the Wizard Gandalf, in flashback. The chapter parallels the far simpler Beorn chapter in The Hobbit, which similarly presents a culture-clash of modern with ancient. The Tolkien scholar Tom Shippey calls the chapter "a largely unappreciated tour de force". The Episcopal priest Fleming Rutledge writes that the chapter brings the hidden narrative of Christianity in The Lord of the Rings close to the surface.

The Lord of the Rings is an epic high fantasy novel by the English author and scholar J. R. R. Tolkien. Set in Middle-earth, the story began as a sequel to Tolkien's 1937 children's book The Hobbit, but eventually developed into a much larger work. Written in stages between 1937 and 1949, The Lord of the Rings is one of the best-selling books ever written, with over 150 million copies sold.
