Sarah Ann McLachlan, OC, OBC (born January 28, 1968) is a Grammy-winning Canadian musician, singer and songwriter.

She is known for the emotional sound of her ballads. Some of her most popular songs include "Angel", "Building a Mystery", "Adia", "Possession", "Fallen", "I Will Remember You", and "World on Fire". As of 2006, she has sold over 40 million albums worldwide. Her best-selling album to date is Surfacing, for which she won eight Juno Awards and three Grammy Awards. In addition to her personal artistic efforts, she founded the Lilith Fair tour, which showcased female musicians in the late 1990s.

Her 1991 album, Solace, was her mainstream breakthrough in Canada, spawning the hit singles "The Path of Thorns (Terms)" and "Into the Fire". Solace also marked the beginning of her partnership with Pierre Marchand. Marchand and McLachlan have been collaborators ever since, with Marchand producing all of McLachlan's albums and occasionally co-writing songs.

1994's Fumbling Towards Ecstasy was an immediate smash hit in Canada. From her Nettwerk connection, her piano version of the song "Possession" was included on the first Due South soundtrack in 1996. Over the next two years, Fumbling Towards Ecstasy quietly became McLachlan's international breakthrough as well, scaling the charts in a number of countries.

Following the success from Fumbling Towards Ecstasy, McLachlan returned in 1997 with Surfacing, her best selling album to date. Earning her two Grammy awards and four Junos, the album has since sold over 11 million copies worldwide and brought her much international success
