Peter, Paul and Mary was an American folk group formed in New York City in 1961, during the American folk music revival phenomenon. The trio was composed of tenor Peter Yarrow, baritone Noel Paul Stookey and alto Mary Travers. The group's repertoire included songs written by Yarrow and Stookey, early songs by Bob Dylan as well as covers of other folk musicians. After the death of Travers in 2009, Yarrow and Stookey continued to perform as a duo under their individual names.

Mary Travers said she was influenced by Woody Guthrie, Pete Seeger, and the Weavers.In the documentary Peter, Paul & Mary: Carry It On — A Musical Legacy members of the Weavers discuss how Peter, Paul and Mary took over the torch of the social commentary of folk music in the 1960s.

The group was inducted into the Vocal Group Hall of Fame in 1999. Peter, Paul and Mary received the Sammy Cahn Lifetime Achievement Award from Songwriters Hall of Fame in 2006.
