"Love Is All We Need" is a song by American singer Mary J. Blige, with a guest rap from Nas. It was written by Blige, Nas, James Harris III, and Terry Lewis for Blige's third studio album, Share My World (1997), while production was helmed by Jimmy Jam & Terry Lewis. The song contains a sample of the song "Moonchild" (1985) as performed by American singer Rick James. With its more buoyant tone, it stood in conspicuous contrast to much of the more dark-rooted material featured on Blige's earlier albums.
The song was released by MCA Records as the album's lead single and earned generally positive reviews from music critics. It became Blige's second song to reach the top of the US Billboard Dance Club Play chart, and it also peaked with the top five of the UK R&B Singles Chart and within the top 10 of the New Zealand Singles Chart. A remix of "Love Is All We Need" features a separate rap cameo by Foxy Brown and a vocal interpolation of Diana Ross' "Do You Know Where You're Going To (Theme from Mahogany)".
