Bob Marley and the Wailers was a Jamaican reggae band led by Bob Marley. It developed from the earlier ska vocal group, the Wailers, created by Marley with Peter Tosh and Bunny Wailer in 1963. By late 1963 singers Junior Braithwaite, Beverley Kelso, and Cherry Smith had joined on. By the early 1970s, Marley and Bunny Wailer had learned to play some instruments and brothers Aston "Family Man" Barrett (bass) and Carlton Barrett (drums), had joined the band. After Bunny Wailer and Peter Tosh left the band in 1974, Marley began touring with new band members. His new backing band included the Barrett brothers, Junior Marvin and Al Anderson on lead guitar, Tyrone Downie and Earl "Wya" Lindo on keyboards, and Alvin "Seeco" Patterson on percussion. The "I Threes", consisting of Judy Mowatt, Marcia Griffiths, and Marley's wife, Rita, provided backing vocals.

The Wailers were formed when self-taught musician Hubert Winston McIntosh (Peter Tosh) met the singers Neville Livingston (Bunny Wailer), and Robert Nesta Marley (Bob Marley) in 1963.

Bob Marley and the Wailers, Peter Tosh, and Bunny Wailer all enjoyed considerable success as reggae music continued to gain popularity during the 1970s and 1980s. One of the last performances that included Marley was in 1980 at Madison Square Garden. Several of the group's members have died subsequent to Marley's death in 1981: Carlton Barrett and Tosh (both murdered) in 1987, Braithwaite in 1999, Smith in 2008, and Earl Lindo in 2017. Bunny Wailer and Beverley Kelso are the only surviving members of the group's original line-up.
