The Iron Mountains or Ered Engrin were an immense mountain range in the north.
Of old the Iron Mountains connected the Blue Mountains (Ered Luin) of the West to the Red Mountains (Orocarni) of the East, but in the wars between the Valar and Melkor the mountain range was distorted.
After the War of Wrath the Iron Mountains were broken and disappeared for a great part of their length.
Remnants of the range in the East could perhaps be all the northern mountain ranges of Eriador and Rhovanion: the Mountains of Angmar, Gundabad, the Ered Mithrin, and the Iron Hills, still occupied by Orcs and Dragons until the Third Age.
