Which J.R.R. Tolkien work contains the tragedy of Túrin Turambar in its most complete standalone form?

The Children of Húrin contains the most complete standalone form of the tragedy of Túrin Turambar in J.R.R. Tolkien’s published works.

Published in 2007, the book was edited by Christopher Tolkien from versions of the story that Tolkien wrote across several decades. It presents the tale of Túrin and his sister Nienor, children of Húrin, during the First Age wars against Morgoth. Their lives are shaped by exile, mistaken identity, and Morgoth’s curse.

The story is related to material in The Silmarillion, Unfinished Tales, and Tolkien’s earlier long poems. The 2007 volume does not invent a wholly new narrative; it gathers and arranges existing writings into a continuous presentation, with Christopher Tolkien supplying editorial transitions and notes.

Túrin is sometimes compared with figures from classical tragedy, particularly because pride, fate, and tragic misunderstanding drive the story. The title refers to both Túrin and Nienor, not only to their father Húrin.
