Glaurung is a fictional character in J. R. R. Tolkien's fictional Middle-earth legendarium. He is introduced in The Silmarillion as the first of the Dragons. He is also the main antagonist, along with Morgoth, in The Children of Húrin. He was known as The Deceiver, The Golden, The Great Worm and the Worm of Greed.

Glaurung was a very powerful dragon, if not the most magical. According to Tolkien, he sired the rest of his race, or at least the brood of Urulóki, wingless fire-breathing dragons. He was bred by Morgoth from some unknown stock and was the first dragon to appear outside of Angband.

In 455 First Age Glaurung led the attack of fire that defeated the Noldorin Elves and their allies and broke the Siege of Angband in the Battle of Sudden Flame, the Dagor Bragollach. In 472 during the Battle of Unnumbered Tears, Nírnaeth Arnoediad, Glaurung led the final reserve and the beasts of Angband in an attack that prevented the joining of the two Elven-hosts, breaking and routing the Host of the sons of Fëanor, resulting in the total defeat of the Union of Maedhros. During this battle Glaurung was stabbed in his vulnerable belly by the Dwarf-king Azaghâl and fled back to Angband.
