Brigyn are a Welsh music act from North Wales, consisting of the brothers Eurig Roberts and Ynyr Roberts.

The brothers formed Brigyn in November 2004 with the release of their eponymous debut album. Released on the Gwynedd label Gwynfryn Cymunedol, the album received considerable airplay on Radio Cymru; one of the tracks, 'Sonar' was selected by BBC Radio 1 DJ Huw Stephens for inclusion on the Dan Y Cownter showcase CD released by the Welsh Music Foundation in 2005. Later that year, a second album, Brigyn2, was also released on the Gwynfryn Cymunedol label with the album launch party hosted inside a tree!

In 2006, Brigyn toured Wales extensively, playing the Sesiwn Fawr festival in Dolgellau in July and the Green Man Festival later in the summer. A tour of Ireland soon followed. Also in 2006, the remix CD Ailgylchu (Recycle) was released, containing remixes by Welsh underground artists of Brigyn songs.

Brigyn achieved prominence in the media through successfully obtaining the permission of Leonard Cohen to release a Welsh-language version of his 1984 song "Hallelujah".
