This is a list of choirs that sing at least part of their repertoire in a Celtic language. Celtic choirs keep alive Celtic music traditions and language, bringing them to a wider audience and reinforcing the learning of Celtic languages. Choirs compete at Celtic festivals such as the National Mod in Scotland and Welsh Eisteddfod. The London Welsh Male Voice Choir and the London Welsh Rugby Club Choir sang the Olympic Anthem at the closing ceremony of the 2012 London Olympics. For choirs in the UK, please see the separate entries for each country. The choirs sing in Breton (Brezhoneg), Cornish (Kernewek), Irish (Gaeilge), Manx Gaelic (Gaelg), Scottish Gaelic (Gaidhlig) or Welsh (Cymraeg).
