The participation of Wales in Eurovision Choir began in Riga, Latvia, at the Eurovision Choir of the Year 2017. Sianel Pedwar Cymru (S4C) a member organisation of the European Broadcasting Union (EBU) are responsible for the selection process of their participants, for their debut in 2017. The first representative to participate for the nation at the 2017 edition were selected on 9 April 2017 during a national final show entitled Côr Cymru (English: Choir of Wales) (actually the English would be Welsh Choirs, as that's what the show is known as to Welsh speakers). This was the second time in any of the Eurovision Network events that the United Kingdom has not participated as a unified state after Jeux Sans Frontières in 1994.
