Thráin II is a fictional character in J. R. R. Tolkien's legendarium. He is first mentioned in The Hobbit and more of his history is given in Unfinished Tales.

A king of the Dwarves, Thráin was the son of Thrór and father of Thorin Oakenshield and Dís. A Longbeard and direct descendant of Durin, he became heir of the lost King under the Mountain and King of Durin's Folk in exile as Thráin II after his father was killed in Moria by the Orc Azog.

Tolkien derived the name Thráin from the Old Norse dwarf-name Þráinn, which aptly means yearner.

Thráin does not appear as a character in The Hobbit, but Gandalf supplies his backstory. Thráin and his kin fled their kingdom of Erebor when the dragon Smaug descended on it. He subsequently acquired a map which showed a secret entrance to Erebor, and later he gave this map to Gandalf. More of Thráin's story is told in Appendix A:III of The Lord of the Rings, and in Unfinished Tales.

Thráin was born in T.A. 2644 the son and heir of Thrór, King under the Mountain. His sons Thorin Oakenshield and Frerin and his daughter Dís were also born in Erebor. In 2770 the whole family went into wandering following the sack of Erebor.
