"Spirit of the Boogie" is a funk/soul song recorded by Kool & the Gang as the title track for their 1975 album.

Daryl Easlea of the BBC said the song "showcases Claydes Smith’s tight, crunchy guitar grit and occasional member Donald Boyce’s "Boogie Man" vocals, as well as the Gang’s trademark group chants.

Ronald Bell’s wayward synth gives it the requisite in-era cosmic edge.

"[1] Amy Hanson of Allmusic proclaimed Spirit of the Boogie "is quintessential Kool & the Gang -- fiery funk which is kept in check by rhythm and chant.

"[2] Record World said that the band's "jazz/rock expertise produces their mightiest outing since 'Hollywood Swingin'.
