Extension of a Man is the final studio album released by the R&B/soul singer Donny Hathaway on Atco Records in 1973.

It is noted for including a young Stanley Clarke of Return to Forever on a couple of tracks, as well as drummer Fred White, brother to Earth, Wind & Fire's Maurice White, who worked with Hathaway in Chicago in the early days.

All tracks composed by Donny Hathaway; except where indicated "Lord Help Me" was originally only released as a B-side to the single "I Love You More Than You'll Ever Know".

It did not feature on Extension of a Man until the 1993 Compact Disc re-release.

The opening instrumental track pays homage to the melody of "Here Comes De Honey Man" from The Gershwin's Porgy and Bess.
