"Don't Think Twice, It's All Right" is a song written by Bob Dylan in 1962 and released the following year on his album The Freewheelin' Bob Dylan and as the B-side of the single "Blowin' in the Wind". The song was covered by several other artists, including Waylon Jennings in 1964, Emilie-Claire Barlow in her 2010 album The Beat Goes On and Peter, Paul and Mary, who released it as a single, which reached the Top 10 of the Billboard Hot 100.

The Freewheelin' Bob Dylan is the second studio album by American singer-songwriter Bob Dylan, released on May 27, 1963, by Columbia Records. Whereas his self-titled debut album Bob Dylan had contained only two original songs, this album represented the beginning of Dylan's writing contemporary lyrics to traditional melodies. Eleven of the thirteen songs on the album are Dylan's original compositions. It opens with "Blowin' in the Wind", which became an anthem of the 1960s, and an international hit for folk trio Peter, Paul and Mary soon after the release of the album. The album featured several other songs which came to be regarded as among Dylan's best compositions and classics of the 1960s folk scene: "Girl from the North Country", "Masters of War", "A Hard Rain's a-Gonna Fall" and "Don't Think Twice, It's All Right".
