Train is an American pop rock band from San Francisco that was formed in 1993. As of 2025, the band consists of Pat Monahan (lead vocals), Taylor Locke (guitar, vocals), Hector Maldonado (bass, vocals), Jerry Becker (keyboards, guitar), and Matt Musty (drums).

With a lineup that included original members Monahan, Rob Hotchkiss, Jimmy Stafford, Scott Underwood, and Charlie Colin, the band achieved mainstream success with their debut album Train. The album was released in 1998 with the hit "Meet Virginia". Train's 2001 album, Drops of Jupiter, contained the lead single "Drops of Jupiter (Tell Me)". The single won two Grammy Awards in 2002, and the album was certified double platinum. Train's third studio album, My Private Nation, released in 2003, was certified platinum in the United States with the hit "Calling All Angels". Following the departures of Hotchkiss and Colin, the band released their fourth album, For Me, It's You in 2006, with Brandon Bush (keyboards) and Johnny Colt (bass). Despite a generally positive reception from critics, the album was commercially unsuccessful. Because of this, Train went on a three-year hiatus from recording any new music.

In late 2009, Train released the album Save Me, San Francisco, from which the album's three singles—the RIAA 11× platinum-certified international hit "Hey, Soul Sister", "If It's Love" and "Marry Me"—reached numbers 3, 34, and 34, respectively, on the Billboard Hot 100. The album was certified gold by both the RIAA and ARIA. In April 2012, Train released California 37. The first single from the album, entitled "Drive By", reached number 10 on the Billboard Hot 100 and was a Top 10 hit in the UK. This album was followed by Bulletproof Picasso (2014), Christmas in Tahoe (2015), Train Does Led Zeppelin II (2016), and A Girl, a Bottle, a Boat (2017). Their album AM Gold was released on May 20, 2022.

Train has sold over 10 million albums and 30 million tracks worldwide.
