Mount Gundabad was a mountain adjacent to the northern reaches of the Misty Mountains. It was revered by the Dwarves but usually occupied by Orcs.

From the northern part of the Vales of Anduin, Mount Gundabad appeared to be the northern endpoint of the Misty Mountains and the western endpoint of the Grey Mountains, although slightly separated from both ranges. In actuality, the Misty Mountains continued past Mount Gundabad in a north-westerly direction (this extension was known as the Mountains of Angmar). In all maps the mountain was shown as having three conjoined peaks. Bordering Forodwaith to the north, the mountain undoubtedly had a cold climate.
