Cân i Gymru (English: A Song for Wales, Welsh pronunciation: [ˈkaːn i ˈɡəmrɨ]) is a Welsh-language television talent competition that is broadcast annually on S4C. It was first introduced in 1969 when BBC Cymru wanted to enter the Eurovision Song Contest.^{[citation needed]} The winner of the contest represents Wales at the annual Pan Celtic Festival held in Ireland and is also awarded a cash prize (which varies from year to year).

Cân i Gymru was presented to Wales under the name Cân Disc a Dawn, a competition based around the Welsh language pop music show Disc a Dawn [cy] (as seen on Victor Lewis Smith's TV Offal), for the first time in 1969. At the time, Meredydd Evans, head of light entertainment at BBC Cymru Wales, hoped that the winning song would be able to compete in the Eurovision Song Contest, although the BBC in London decided in the end that only one song from Britain would compete.^[1]

Eight programmes were broadcast in the series to select a Song for Wales with seven songs in each, performed by well-known singers of the time. The public voted by sending in letters and the song with the most votes went through to the final. The last programme was broadcast on 5 June 1969 throughout Britain on BBC1 under the title Song for Wales and was presented by Ronnie Williams in Welsh and English.^[2] A panel then chose the winning song on the night.^[3] The programme was also part of the BBC's provision for the Investiture of Prince Charles which would take place on 1 July 1969.

Following the establishment of the Pan Celtic Festival in Ireland in the early 1970s the Festival's Wales Committee started the Cân i Gymru competition once again in order to choose a song to represent Wales in the Celtavision competition. There was no competition in 1973. Initially the media in Wales did not have much interest in the competition. Cân i Gymru was not broadcast live on television, and a panel voted to choose the winners. For example, the 1980 competition was held at Bar Cefn yr Angel in Aberystwyth and was broadcast on BBC Radio Cymru.

By 1982 the competition was back on television but a panel still chose the winner. The winning song is now chosen by a vote where members of the public phone for their favorite song. In 2024, the prize was £5,000 with £3,000 for second place and £2,000 for third place. The winner has the opportunity to go on to compete in Celtavision, held in Ireland as part of the Pan Celtic Festival.

Unlike the majority of singing competitions in Europe, the emphasis is on the composer of the song rather than the performer. A compilation album was released in 2005 by Welsh record label Sain containing all the tracks that won the competition from its inception in 1969 to 2005.^[4] This was followed by individual compilation albums for the 2006 and 2007 competitions, both of which were released by TPF Records.
