Dark Iron Dwarves are a hostile faction of dwarves from the World of Warcraft universe.

The Dark Iron clan have long been in opposition to the Bronzebeard clan and once tried, unsuccessfully, to seize control of Ironforge from both the Bronzebeards and the Wildhammer clans.

Now followers of the elemental Ragnaros the Dark Iron Clan reside in Blackrock Mountain and have their own monarchy, however with the events of the Cataclysm brought forth by Deathwing this order is no longer universal and some Dark Iron Dwarves have redeemed themselves and become allies of the Alliance, other Dark Iron Dwarves have opted for allying with the Twilight Hammer instead.
