Dark Mountain, formerly also known as Black Mountain, is a mountain in the Tanzilla Plateau of the Northern Interior of British Columbia, Canada, located northeast of the settlement of Dease Lake, near Cry Lake.
Before 1937 Dark Mountain was known as Black Mountain. The Canadian Geological Survey recommended a name change to avoid confusion with several similarly named features, see Black Mountain (disambiguation).
