The Derryveagh Mountains ({{Langx|ga|Cnoic Dhoire Bheatha}}) are the major mountain range in County Donegal, Ireland. It makes up much of the landmass of the county and is the area of Ireland with the lowest population density. The mountains separate the coastal parts of the county, such as Gweedore and Glenties, from the major inland towns such as Ballybofey and Letterkenny. Its highest peak is Errigal.{{cite web|url=http://www.monreaghulsterscotscentre.com/poisoned-glen/ |title=The mystery of the Poisoned Glen |publisher=Monreagh Heritage Centre |accessdate=4 September 2016}}
