"Love Hangover" was the fourth number one single for Motown singer Diana Ross. Ross recorded "Love Hangover" in 1975. 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.

The song was written by Pamela Sawyer and Marilyn McLeod as a disco number. Producer Hal Davis recorded the instrumental track in 1975 thinking it ideal for Marvin Gaye or Diana Ross, who were his two favorite vocalists to work with. He thought Diana would be sexier on it, so he recorded the song with her. Background vocals on the track were provided by Motown's in-house trio, The Andantes. Studio musicians included James Gadson on drums, Henry E. Davis (of the band L.T.D.) on bass, and Joe Sample on keyboards.

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.

The song was released on the Diana Ross LP in February, 1976. The lead single from the album was "I Thought It Took A Little Time." Singing group The 5th Dimension also released "Love Hangover" as a single. Motown then issued Ross' version on 45. Both versions entered the chart the same day. By the time Ross' version of "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.
