"Slow Train" is a song written by Bob Dylan that first appeared on his 1979 album Slow Train Coming. In the United States, it was released as the follow-up single to "Gotta Serve Somebody." It was also released as the lead song from Dylan's 1989 live album with the Grateful Dead, Dylan & the Dead. Music critic Paul Williams has called it "the one track [on Slow Train Coming] that must be listened to again and again and again, inexhaustible, essential." Rolling Stone editor Jann Wenner has called it "nothing less than Dylan's most mature and profound song about America".

Slow Train Coming is the nineteenth studio album by American singer-songwriter Bob Dylan, released on August 20, 1979, by Columbia Records. It was Dylan's first album following his conversion to Christianity, and the songs either express personal faith, or stress the importance of Christian teachings and philosophy. The evangelical nature of the record alienated many of Dylan's existing fans; at the same time, many Christians were drawn into his fan base. Slow Train Coming was listed at No. 16 in the 2001 book CCM Presents: The 100 Greatest Albums in Christian Music.
