"Sleeping with the Light On" is a song by English pop rock band Busted. It was the first song which band members James Bourne and Matt Willis wrote together. It was recorded in 2002 for their debut album Busted, and later released on 11 August 2003 as the album's fourth British single. It reached number three on the UK Singles Chart. In 2014, McBusted performed this song in an acoustic live session.

"Sleeping with the Light On" was written by Busted members James Bourne and Matt Willis and produced by Steve Robson and Graham Stewart.

The song was heavily remixed for its release as a single; the first chorus is more forceful than on the album version. This "New Version" was also used for the song's music video. Among the single B-sides were a non-album track, "Last Summer"; a medley of Busted's first three singles, which was previously performed on CD:UK, and a live recording of "You Said No" with 40,000 fans singing the chorus. The song was performed on Blue Peter, CD:UK, Popworld and Top of the Pops Saturday.
