"It's All Over Now, Baby Blue" is a song written and performed by Bob Dylan and featured on his Bringing It All Back Home album, released on March 22, 1965, by Columbia Records. The song was recorded on January 15, 1965, with Dylan's acoustic guitar and harmonica and William E. Lee's bass guitar the only instrumentation. The lyrics were heavily influenced by Symbolist poetry and bid farewell to the titular "Baby Blue". There has been much speculation about the real life identity of "Baby Blue", with possibilities including Joan Baez, David Blue, Paul Clayton, Dylan's folk music audience, and even Dylan himself.

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.
