"Love Hangover" was the fourth number one single for Motown singer Diana Ross. It was released in March 1976, and rose to number one on the Billboard Hot 100, Hot Soul Singles and Hot Dance Club Play charts simultaneously.

Written by Pamela Sawyer and Marilyn McLeod, the song had been originally recorded by the The 5th Dimension as a disco number. The Motown staff believed that it would be perfect for Ross to record. Ross, like her soul contemporaries Aretha Franklin and Marvin Gaye, initially resented the new musical movement but eventually agreed to record the song.

Producer Hal Davis instructed the song's engineer Russ Terrana to install a strobe light so that Ross could be in the "disco" mindset. As the song changed from ballad to uptempo, Ross became more comfortable with the material; she hummed, sang bit parts, laughed, danced around and even imitated Billie Holiday. The carefree and sensual nature of Ross' vocals and the music's direction helped to sell the song.

When The 5th Dimension and Ross both released the tune simultaneously, Ross's version charted higher. By the time "Love Hangover" went to number one, Ross had reinvented herself as a disco diva and the 5th Dimension's version had peaked at number 80. It won Ross a Grammy nomination for Best R&B Female Vocal Performance.

Motown released versions of Ross's version in 1988 (remixed by the British team PWL) and 1993 (remixed by Frankie Knuckles for the album Diana Extended: The Remixesand by Joey Negro for a single).

Almighty Records released a remixed version in 2007 (remixed by the UK team Almighty).

In addition to being covered by the 5th Dimension, the song was also released as a single by the Associates, a British New-wave band. It reached #21 on the UK chart in 1982. Players Association also covered the track in 1977.

British soul singer Pauline Henry (former lead vocalist of "The Chimes") recorded a contemporary version of the track in 1995 (released as a single); singer Jody Watley recorded a downtempo version for her 2006 album, The Makeover; while Australian singer-songwriter Tina Arena recorded a version in 2007 for her album Songs of Love & Loss.

Mariah Carey performed the song in a concert tribute to Diana Ross (2000), and Stephanie Edwards sang it on the sixth season of American Idol.

The song would become part of the hip-hop lexicon via sampling by Will Smith, Master P, Monica, Janet Jackson, Bone Thugs-N-Harmony, French artist MC Solaar and Emily King, who made use of it for her 2007 debut album, East Side Story, in the song Walk in My Shoes.

Guns N' Roses lead singer Axl Rose sang the chorus of "Love Hangover" during an instrumental interlude in the song "If the World" on the Asian leg of the Chinese Democracy World Tour 2009/2010.

Mariah Carey performed a mix of "Love Hangover" and her #1 single "Heartbreaker" on her Angels Advocate Tour between 2009 and 2010.
