"All the Man That I Need" is the second single from pop singer Whitney Houston's third album I'm Your Baby Tonight.

The song was written by Dean Pitchford and Michael Gore; a version was released by Linda Clifford a decade earlier. Houston's music video for this song was directed by Peter Israelson (the same director for her videos "Greatest Love of All" and "Where Do Broken Hearts Go.") Sister Sledge also had a minor R&B hit with the song in 1982 peaking at number forty-five on the soul charts..

Released in December 1990, "All the Man That I Need" entered the Billboard Hot 100 Singles Chart at number fifty-three. Within four weeks of its release, it ascended to the top of the charts, becaming Houston's ninth number one Hot 100 single. It held the summit for two weeks, from February 23 to March 8. It remained in the Top 40 for fifteen weeks. It also topped the Hot 100 Single Sales and Hot 100 Airplay charts, her first song to achieve this feat since "Where Do Broken Hearts Go" in 1988. Additionally, the single also reached number one for four weeks on the Adult Contemporary Chart, and for two weeks on the R&B Chart. Also, the song was notable as being Houston's first release to top all the charts it was eligible on. It was ranked sixteen on the Billboard Hot 100 Year End Charts for 1991.

Internationally, the song was more moderately successful, except in the UK, where it reached #13. It reached twenty-eight in both France and Switzerland, and number thirty-seven in Germany.
