Lisa Gerrard (born 12 April 1961) is an Australian musician, singer and composer who rose to prominence as part of the music group Dead Can Dance with music partner Brendan Perry.

Since her career began in 1981, Gerrard has been involved in a wide range of projects. She received a Golden Globe Award for the music score to the film Gladiator, on which she collaborated with Hans Zimmer on such songs as "Now We Are Free." With respect to such work she has said, "I sing in the language of the Heart. It's an invented language that I've had for a very long time. I believe I started singing in it when I was about 12. Roughly that time. And I believed that I was speaking to God when I sang in that language."
