Clannad are a Grammy Award-winning Irish musical group, from Gweedore (Gaoth Dobhair), County Donegal. Their music has been variously described as bordering on folk and folk rock, Irish, and New Age. They are known for performing in various languages, including English, Latin, Gàidhlig, Mohican and most of all in their native tongue, Irish.

Clannad are Moya Brennan (born Máire Ní Bhraonáin), Ciarán Brennan (born Ciarán Ó Braonáin), Noel Duggan (born Noel Ó Dúgáin) and Pádraig Duggan (born Pádraig Ó Dúgáin). Pól Brennan (born Pól Ó Braonáin) left the group in 1990 in order to pursue a solo career.

Clannad first made their mark in the folk and traditional scene in the 1970s in Ireland and Europe. They subsequently went on to bridge the gap between traditional celtic music and pop music in the 1980s and 1990s with albums such as Macalla and Anam.

During their successful career they toured the world extensively and gained fans in every major territory. Lead singer Moya Brennan and her sister Enya have also enjoyed huge success as solo artists. The band won a Grammy Award in 1998 for Best New Age Album, and their record sales exceed the 15 million mark.

They are also regarded as the band which, for the first time, put Irish traditional music and the Irish language on the world stage and paved the way for many other Irish artists.

Ten years after disbanding, the five original members of Clannad reunited on stage at the Celtic Connections Festival in February 2007 in Glasgow. They expressed their wishes to release a new studio album, but no official announcements have been made as yet..

Moya, Ciarán, Noel and Pádraig embarked on their first UK tour in over 10 years in March 2008, starting in Gateshead.
