Gweedore (officially known by its Irish language name,) is an Irish-speaking parish located on the Atlantic coast of County Donegal, Ireland. Gweedore stretches some 16 miles from Meenaclady in the north to Crolly in the south and around 9 miles from Dunlewey in the east to Magheraclogher in the west, and is one of Europe's most densely populated rural areas. It is the largest Irish-speaking parish in Ireland with a population of around 4,065, and is also the home of the northwest regional studios of the Irish-language radio service RTÉ Raidió na Gaeltachta, as well as an external campus of National University of Ireland, Galway. Gweedore includes the villages Bunbeg, Derrybeg, Dunlewey, Crolly and Brinalack, and sits in the shade of Donegal's highest peak, Errigal.
Gweedore is known for being a cradle of Irish culture, with old Irish customs, traditional music, theatre, Gaelic games and the Irish language playing a central and pivotal role in the lives of the local people. This, along with its scenery and many beaches, has made the area a popular tourist destination, especially with visitors from Northern Ireland. Gweedore and the neighbouring districts of Cloughaneely and the Rosses are collectively known locally as "the three parishes", they form a social and cultural region distinct from the rest of the county, with Gweedore serving as the main centre for socialising and industry.
