Malin Head, Coastal headland in County Donegal, Ireland

Malin Head is the northernmost point of mainland Ireland, a broad headland in County Donegal whose grassy plateau ends in steep, dark rock faces fractured into vertical columns. The northern tip is called Dunalderagh, at latitude 55.38ºN, about 16 km north of Malin village. Small white birds can be seen on the rock face.

During World War II the British government installed radio direction finding equipment at this cape to monitor North Atlantic naval activities. This military use shaped the site for several years.

Malin Head gives its name to the Malin sea area, whose conditions are read in the BBC Shipping Forecast, and its weather station is one of 22 whose reports are broadcast there. In autumn, birdwatchers gather on the headland to watch gannets, shearwaters, skuas and auks on their southward migration; black-browed albatross and fea's petrel have been recorded. Basking sharks and a resident pod of bottle-nosed dolphins are watched from the cape.

Malin Head lies about 16 km north of Malin village on the Inishowen peninsula, reached by local roads; the northern tip is Dunalderagh at 55.38ºN. High winds and storms occur for much of the year, so check conditions before walking the exposed cliff tops. The 1805 tower on Altnadarrow, or Tower Hill, and the nearby '80 EIRE' stone marker are the main landmarks to orient by.

The highest wind speed recorded at Malin Head's weather station reached 181.5 km/h on 16 September 1961, when Hurricane Debbie caused damage along Ireland's west coast. The station's reports are among 22 broadcast in the BBC Shipping Forecast.
