Peter, Paul and Mary were an American folk group formed in New York City in 1961 during the American folk music revival phenomenon. The trio consisted of Peter Yarrow, Paul Stookey, and Mary Travers. The group's repertoire included songs written by Yarrow and Stookey, early songs by Bob Dylan, and covers of other folk musicians. They were enormously successful in the early- and mid-1960s, with their debut album topping the charts for weeks, and helped popularize the folk music revival. After the death of Travers in 2009, Yarrow and Stookey continued to perform as a duo under their individual names.

Contemporary folk music refers to a wide variety of genres that emerged in the mid 20th century and afterwards which were associated with traditional folk music. Starting in the mid-20th century, a new form of popular folk music evolved from traditional folk music. This process and period is called the (second) folk revival and reached a zenith in the 1960s. The most common name for this new form of music is also "folk music", but is often called "contemporary folk music" or "folk revival music" to make the distinction. The transition was somewhat centered in the United States and is also called the American folk music revival. Fusion genres such as folk rock and others also evolved within this phenomenon. While contemporary folk music is a genre generally distinct from traditional folk music, it often shares the same English name, performers and venues as traditional folk music; even individual songs may be a blend of the two.
