Niall Vallely is an Irish musician, born about 1970 in Armagh, Northern Ireland. In 1966 his parents, Brian and Eithne Vallely had founded the Armagh Piper's Club, but he chose to learn the concertina instead, from the age of seven. His brother Cillian plays the uillean pipes and low whistle, learning from Mark Donnelly. Another of his brothers, Caoimhin, plays classical piano, tin whistle and fiddle. In 1990 Niall founded the group Nomos, which released two albums before breaking up in 2000. In 1992 Niall completed a degree in music at University College, Cork. Caoimhin also studied at UCC, then took an M.A. in Traditional Music Performance at the University of Limerick.
In 1998 Niall released a solo album of contemporary and traditional tunes from Ireland and Scotland. He also produced and composed the tunes for Karan Casey's album for children "The Seal Maiden".

In 1999 he released his debut solo album, "Beyond Words", and in 2003 "Callan Bridge" with his brother Cillian on uilleann pipes. Over the past few years Niall has also been spending a lot of time writing new music. In 2007 he was commissioned by the BBC to compose music for a major TV series on the Flight of the Earls. The resulting piece was then premiered at the Grand Opera House in Belfast as part of the Belfast Festival at Queens and had a subsequent performance at the Irish College in Louvain, Belgium, as part of their Flight of the Earls celebrations. In 2008 he composed an electro-acoustic piece entitled "Rakish" based on the music of travelling piper Johnny Doran which was premiered at the William Kennedy Piping Festival in Armagh.
