"Subterranean Homesick Blues" is a song by Bob Dylan, recorded on January 14, 1965, and released as a single by Columbia Records, catalogue number 43242, on March 8. It is the first track on the album Bringing It All Back Home, released some two weeks later. It was Dylan's first Top 40 hit in the United States, peaking at number 39 on the Billboard Hot 100. It also entered the Top 10 of the UK Singles Chart. The song has subsequently been reissued on numerous compilations, the first being the 1967 singles compilation Bob Dylan's Greatest Hits. One of Dylan's first electric recordings, "Subterranean Homesick Blues" is also notable for its innovative music video, which first appeared in D. A. Pennebaker's documentary Dont Look Back. An acoustic version of the song, recorded the day before the single, was released on The Bootleg Series Volumes 1–3 1961–1991.

Bob Dylan is an American singer-songwriter. Often considered to be one of the greatest songwriters in history, Dylan has been a major figure in popular culture over his 60-year career. He rose to prominence in the 1960s, when his songs "Blowin' in the Wind" (1963) and "The Times They Are a-Changin'" (1964) became anthems for the civil rights and antiwar movements. Initially modeling his style on Woody Guthrie's folk songs, Robert Johnson's blues, and what he called the "architectural forms" of Hank Williams's country songs, Dylan added increasingly sophisticated lyrical techniques to the folk music of the early 1960s, infusing it "with the intellectualism of classic literature and poetry". His lyrics incorporated political, social, and philosophical influences, defying pop music conventions and appealing to the burgeoning counterculture.
