Meav Ne Mhaolchatha is an Irish singer and recording artist specializing in the traditional music of her homeland, who has been one of the original soloists in the musical ensemble Celtic Woman.

A native of Dublin, Meav attended the city's Trinity College. Between 1994 and 1998 she was a principal soloist with the world-renowned Irish chamber choir Anena, and subsequently toured the United States as a soloist with the RTE Concert Orchestra. Still later, she toured South Africa with Lord of the Dance and gave concerts in Japan and South Korea.

Along with the other members of Celtic Woman, Meav gained musical stardom upon the ensemble's founding and almost immediate fame in 2004. Her singing is a prominent element of Celtic Woman's three CDs, Celtic Woman, Celtic Woman: A Christmas Celebration, and Celtic Woman: A New Journey. The following year she took maternity leave to await the birth of her first child. Her temporary replacement for Celtic Woman tours, Deirdre Shannon, left the ensemble in February 2006 and Meav returned to record the New Journey CD and participate in tours part-time. On 6 September 2006, a new member, Hayley Westenra, joined Celtic Woman, thus enabling the ensemble to maintain the cast of five female performers by alternating Hayley with Meav during touring periods. Meav committed herself, however, to the 2007 tour, beginning with the first performance on 14 February.
