Solas (Irish: light) is an Irish-American musical group formed in 1994, playing Irish traditional music as well as original compositions, sometimes demonstrating an inclination towards Country music in recent albums.

Their name comes from an Irish word meaning "light". At the time, the band was made up of Séamus Egan, who had already recorded two solo albums as well as a soundtrack to a film; Winifred Horan, a member of Cherish the Ladies; John Doyle, previously a member of Susan McKeown & The Chanting House with Egan; Karan Casey and John Williams. Their first performance was in Georgetown University's Gaston Hall in Washington, D.C. in 1995.
