"Mr. Tambourine Man" is a song written, composed, and performed by Bob Dylan, who released his original version of it on his 1965 album Bringing It All Back Home. The Byrds also recorded a version of the song that they released in the same year as their first single on Columbia Records, reaching number 1 on both the Billboard Hot 100 chart and the UK Singles Chart, as well as being the title track of their debut album, Mr. Tambourine Man. The Byrds' recording of the song was influential in popularizing the musical subgenres of folk rock and jangle pop, leading many contemporary bands to mimic its fusion of jangly guitars and intellectual lyrics in the wake of the single's success.

The Bringing it All Back Home version of "Mr. Tambourine Man" was included on Bob Dylan's Greatest Hits in 1967 and several later Dylan compilation albums, including Biograph, Masterpieces, and The Essential Bob Dylan. The two June 1964 recordings, one with Ramblin' Jack Elliott and the other at Witmark Music, have been released on The Bootleg Series Vol. 7: No Direction Home and The Bootleg Series Vol. 9: The Witmark Demos 1962-1964, respectively. Outtakes from the January 15, 1965 recording session were released on The Bootleg Series Vol. 12: The Cutting Edge 1965-1966 in 2015.  The song has been in Dylan's live concert repertoire ever since it was written, usually as a solo acoustic song, and live performances have appeared on various concert albums and DVDs. An early performance, recorded during a songs workshop at the Newport Folk Festival on July 24, 1964 is included in both Murray Lerner's film The Other Side of the Mirror and the DVD release of Martin Scorsese's documentary No Direction Home. A live performance at New York's Philharmonic Hall dating from October 31, 1964, appeared on The Bootleg Series Vol. 6: Bob Dylan Live 1964, Concert at Philharmonic Hall. During his appearance at the Newport Folk Festival on July 25, 1965, after he was heckled by acoustic folk music fans during his electric set, Dylan returned to play acoustic versions of "Mr. Tambourine Man" and "It's All Over Now, Baby Blue"; this performance of "Mr. Tambourine Man" is also included in The Other Side of the Mirror.  A live version from Dylan's famous May 17, 1966, concert in Manchester, England (popularly but mistakenly known as the Royal Albert Hall Concert) is included on The Bootleg Series Vol. 4: Bob Dylan Live 1966, The "Royal Albert Hall" Concert. Dylan's August 31, 1969 performance of the song at the Isle of Wight Festival appears on Isle of Wight Live, part of the 4-CD deluxe edition of The Bootleg Series Vol. 10: Another Self Portrait (1969-1971). Dylan also played the song as part of his evening set at the August 1, 1971, Concert for Bangladesh, a benefit concert organized by George Harrison and Ravi Shankar. That performance is included on The Concert For Bangladesh album, although it was excluded from the film of the concert. Another live version, from the Rolling Thunder Revue tour of 1975, is on The Bootleg Series Vol. 5: Bob Dylan Live 1975, The Rolling Thunder Revue, while electric band versions from 1978 and 1981 appear, respectively, on Bob Dylan at Budokan and the Deluxe Edition of The Bootleg Series Vol. 13: Trouble No More 1979-1981.
