"Love Train" is a hit single by The O'Jays, written by Kenny Gamble and Leon Huff. Released in 1972, it reached number one on both the R&B Singles and the Billboard Hot 100, in February and March 1973 respectively, number 9 on the UK Singles Chart and was certified gold by the RIAA.

It was The O'Jays' first and only number-one record on the U.S. pop chart. "Love Train" entered the Hot 100's top 40 on 27 January 1973, the same day that the Paris Peace Accords were signed. The song's lyrics of unity mention a number of countries, including England, Russia, China, Egypt and Israel, as well as the continent of Africa.

Recorded at Philadelphia's Sigma Sound Studios, the house band MFSB provided the backing. Besides its release as a single, "Love Train" was the last song on The O'Jays' album Back Stabbers.

The music video shows a group of people forming a chain near a railroad station, while at the same time, some railroad cars are shown in motion. Throughout the video, more people join in the chain, which they call the "Love Train". It was most likely filmed around the Northeast Corridor, as Long Island Rail Road MP75 railcars appear throughout the music video (in which the words "LONG ISLAND" are clearly visible), as well as Amtrak railcars and other railcars. Not much is known about the music video, although it was recorded in 1973.

By early 1974, The Supremes' line up (Wilson, Birdsong and Payne) adopted the song to perform in live appearances. Hall & Oates covered the song for the 1989 soundtrack to the film Earth Girls Are Easy, as well as Daryl Hall and his band joining the 2016 version of the O'Jays in a live version on Hall's "Live from Daryl's House" television show. The Rolling Stones played Love Train on their worldwide Licks Tour during 2002 and 2003. Roots rock 'n' roll band The Yayhoos' cover appeared on their 2006 release, "Put The Hammer Down." Gospel Group Doc McKenzie and the Hi-Lites covered this song in 2003 .In 2011, Alvin and the Chipmunks and The Chipettes covered the song as a bonus track on the Target limited edition of the soundtrack Alvin and the Chipmunks: Chipwrecked: Music from the Motion Picture.
