The Temptations in a Mellow Mood is a studio album by the Temptations, released in 1967 by Gordy Records. Composed primarily of pop standards such as "Ol' Man River" and "For Once in My Life", and similar songs written by Holland-Dozier-Holland and other Motown staff songwriters, the Mellow Mood album was part of Motown chief Berry Gordy's crossover plans for the group. Gordy wanted the Temptations, already the most popular male group among black audiences, to attract a large white fanbase and be able to secure playdates at supper clubs like the Copacabana, where the group had first performed in the summer of 1967.

The Temptations are an American vocal group from Detroit, Michigan, who released a series of successful singles and albums with Motown Records during the 1960s to mid 1970s. The group's work with producer Norman Whitfield, beginning with the Top 10 hit single "Cloud Nine" in October 1968, pioneered psychedelic soul, and was significant in the evolution of R&B and soul music. The band members are known for their choreography, distinct harmonies, and dress style. Having sold tens of millions of albums, the Temptations are among the most successful groups in popular music.
