Gillian Welch (/ˈɡɪliən ˈwɛltʃ/; born October 2, 1967) is an American singer-songwriter. She performs with her musical partner, guitarist David Rawlings. Their sparse and dark musical style, which combines elements of Appalachian music, Bluegrass, and Americana, is described by The New Yorker as "at once innovative and obliquely reminiscent of past rural forms".

Welch and Rawlings have released five critically acclaimed albums. Their 1996 debut, Revival, and the 2001 release Time (The Revelator), received nominations for the Grammy Award for Best Contemporary Folk Album. Their 2003 album, Soul Journey, introduced electric guitar, drums and a more upbeat sound to their body of work. After a gap of eight years, they released their fifth studio album, The Harrow & The Harvest, in 2011, which was also nominated for a Grammy for Best Contemporary Folk Album.
