"Love Hangover" is a song by the Motown singer Diana Ross, recorded in 1975 and released as a single on March 16, 1976. It rose to number one on the Billboard Hot 100 and Hot-Selling Soul Singles. It also hit number one on the Record World disco charts.

Producer Hal Davis instructed the song's engineer Russ Terrana to install a strobe light so that Ross could be in the "disco" mindset.^[3] 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.^[4]

The song was first released on the album Diana Ross in February 1976. Motown initially promoted the album by releasing the single "I Thought It Took a Little Time". Singing group the 5th Dimension released "Love Hangover" as a single. Motown then issued Ross's version as a 7-inch single. Both versions entered the chart the same day. By the time Ross's version of the song reached 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 Female R&B Vocal Performance. It appeared on the soundtrack of the following year's Diane Keaton movie Looking for Mr. Goodbar.

"Love Hangover" reached number one on May 29, 1976. That week, Casey Kasem reported on American Top 40 that Ross had broken the record for the most number-one hits by a female vocalist. With her fourth number one, she passed Connie Francis, Helen Reddy, Roberta Flack, and Cher, each of whom had three.

Ross performed the song on the April 4, 1980 episode of The Muppet Show during its season four run.

The song was remixed several times. A version remixed by Eric Kupper, known as "Love Hangover 2020", hit number one on Billboard's Dance Club Songs chart in March 2020.

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 Remixes and by Joey Negro for a single).

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

New remixes were released in 2020 by Eric Kupper, peaking at number one on March 28 on the Billboard Dance Club chart.^[5]
