"Cloud Nine" is a 1968 hit single recorded by The Temptations for the Motown label. It was the first of their singles to feature Dennis Edwards instead of David Ruffin in the lineup, was the first of producer Norman Whitfield's psychedelic soul tracks, and won Motown its first Grammy Award. The song was written by Whitfield and former Motown artist Barrett Strong.

In 1968, psychedelic rock band Sly & the Family Stone had a hit with their single "Dance to the Music", and Temptations member Otis Williams introduced Norman Whitfield to the band's music. At first, Whitfield did not want to produce anything with such a radically different sound. "I don't want to get into all that crazy shit," he said. "That ain't nothing but a little passing fancy." Within a few weeks, however, he had created the backing tracks for the newest Temptations single, a psychedelic-styled number called "Cloud Nine", and stuck primarily to such songs well into the early 1970s.

Featuring all five Temptations trading lead vocals à la The Family Stone, "Cloud Nine" was a marked departure from the standard Tempts sound: wah-wah guitars and a harder, driving beat propelled the record, as opposed to pianos and strings. The song also features the Cuban percussionist Mongo Santamaria on conga drums. Edwards, Eddie Kendricks and Paul Williams swap leads on the verses, bridges and choruses, such as this example from the first bridge:
