"You're the First, the Last, My Everything" or "You're the First, My Last, My Everything" is a popular song recorded by Barry White. Written by White, Tony Sepe and Peter Radcliffe and produced by White, "You're the First, the Last, My Everything" was White's fourth top ten hit on the Billboard Hot 100 singles chart, reaching #2; it spent a week at #1 on the Billboard Hot Soul Singles chart. The early disco classic made it to number two on the disco/dance charts. In the UK Singles Chart it fared even better, spending two weeks at the top in December 1974. It appeared on White's 1974 album Can't Get Enough.

Radcliffe originally wrote "You're the First, My Last, My Everything" as a country song with the title "You're My First, You're My Last, My In-Between", which went unrecorded for 21 years. White recorded it as a disco song, keeping most of the structure and about two-third of the title, but he rewrote the lyrics.

The song is featured in the films Money Talks (1997; also on its CD soundtrack album, where White had recorded an alternative version, as simply "My Everything" as a duet with Faith Evans), Bridget Jones: The Edge of Reason (2004; also on its CD soundtrack album), Zookeeper (2011), and anachronistically in Tim Burton's film Dark Shadows (2012; also on its CD soundtrack album) as the film was set in 1972, two years before the song was released.
