Celtic Woman is an all-female Irish musical ensemble. Formed in 2004 for a one-time event held in Dublin, Ireland, they started touring internationally as a group after multiple airings on PBS helped boost the group's popularity. Celtic Woman released their debut album Celtic Woman in 2004 and have since released more than twenty albums. Cumulatively, they have sold over nine million records worldwide. The group's line-up, involving vocalists and a fiddler, has changed over the years. Founded with Chloë Agnew, Órla Fallon, Lisa Kelly, Méav Ní Mhaolchatha, and Máiréad Nesbitt, the group consists of Mairéad Carlin, Tara McNeill, Muirgen O'Mahony, and Emma Warren as of July 2023. Celtic Woman has been described as being "Riverdance for the voice." Celtic Woman has been named Billboard World Album Artist of the Year six times.
