Which character is the father of the dragon Smaug in J.R.R. Tolkien’s Middle-earth writings?
Answer
No father is named
J.R.R. Tolkien names no father for the dragon Smaug.
Smaug is introduced in The Hobbit as a great dragon who attacks the Dwarf kingdom under the Lonely Mountain and takes its treasure. Tolkien gives Smaug a detailed personality and history as a thief and destroyer, but does not identify his parentage.
This makes “no father is named” the precise answer rather than the name of another dragon. Glaurung is the father of dragons in Tolkien’s First Age stories, while Ancalagon is another enormous dragon who fought in the War of Wrath. Scatha is a different dragon associated with the Grey Mountains.
Tolkien’s works often provide genealogies for Elves, Men, and Dwarves, but many creatures receive less complete family histories. Smaug’s origin remains unspecified in the published narrative.
