Hot Buttered Soul is the second studio album by American soul musician Isaac Hayes. Released on September 23, 1969, it is recognized as a landmark in soul music.

Hayes' 1968 solo debut, Presenting Isaac Hayes, had been a poor seller for the record label Stax Records, and Hayes was about to return to his behind-the-scenes role as a producer and songwriter, when the label suddenly lost its entire back catalog after splitting with Atlantic Records in May 1968.

Stax executive Al Bell decided to release an almost-instant back catalog of 27 albums and 30 singles at once, and ordered all of Stax's artists to record new material, encouraging some of Stax's prominent creative staff, including Hayes and guitarist Steve Cropper, to record solo albums.

After feeling burned by the retail and creative flop of his first album, Hayes told Bell that he would not record a follow-up or any other album unless he was granted complete creative control. Since Bell had encouraged Hayes to record Presenting... in the first place, he readily agreed.

Much of the final production was done as part of the package of products brought to Detroit by producer Don Davis to expedite the production process. The strings and horns were arranged by Detroit arranger, Johnny Allen. The producers were looking for a sweeping orchestral sound that would enhance the rock solid rhythm tracks. The project strings and horns were recorded at United Sound Studios by engineer Ed Wolfrum with vocals and final mix at Tera Shirma by engineer Russ Terrana. The pre-delay reverberation technique, recorded in part by Terry Manning on the tracking session, had been used at Artie Fields productions in Detroit in late 1950s, and at Columbia Records; it was also used by Wolfrum and others for numerous productions and commercials previous and after the release of this project including the Marvin Gaye What's Going On project, with orchestration also recorded at United. Russ Terrana went on to the engineering staff of Motown Records and was responsible for the recording and mixing of many hits on that label.
