"You're All I Need to Get By" is a song recorded by the American R&B/soul duo Marvin Gaye and Tammi Terrell and released on Motown Records' Tamla label in 1968. It was the basis for the 1995 single "I'll Be There for You/You're All I Need to Get By" from Method Man and Mary J. Blige.

You're All I Need is the second studio album by soul musicians Marvin Gaye and Tammi Terrell, released in August 1968 on Motown-subsidiary label Tamla Records. Highlighted by three hit singles written by Nickolas Ashford and Valerie Simpson, You're All I Need was recorded throughout 1966 and 1967 and features two Top 10 Billboard Hot 100 hits, "Ain't Nothing Like the Real Thing" and "You're All I Need to Get By". It peaked at #60 on the U.S. Billboard 200 Album Chart. You're All I Need was the two singers' final collaboration effort, as Terrell would become ill following recording, before succumbing to a brain tumor in 1970.
