"Love Hangover" is a song by the American singer Diana Ross, recorded in 1975 and released as a single on March 16, 1976.

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

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.

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