"Lay Me Down" is the debut single by English singer Sam Smith and the lead single from his debut studio album In the Lonely Hour (2014). The song was released in the United Kingdom on 15 February 2013. It originally peaked at number 46 on the UK Singles Chart and at number 25 on the US Bubbling Under Hot 100 Singles in 2014. The song was written by Smith, Jimmy Napes and Elviin and produced by Napes and Steve Fitzmaurice.

The song was re-released in February 2015 as the sixth single from the album, this time reaching number 8 on the US Billboard Hot 100 and number 15 on the UK Singles Chart. A third version featuring John Legend recorded for the British charity telethon Comic Relief reached number one in the UK in March 2015.

Musically, according to the sheet music published at musicnotes.com, the song is written in E major, with a tempo of 118 bpm.

The original music video showed Smith and his friends at a casino. Following the announcement of the re-release, it was removed from YouTube and Vevo.

It was announced on 30 January 2015 that Smith would re-release "Lay Me Down" as the sixth single from his album In the Lonely Hour following commercial success with his previous singles. Smith recorded a new version of the song for its re-release with the track's original producers.

The music video for the re-release, which replaced the original, was recorded in St Margaret's Church, Lee, South East London, with the permission of the Rector the Revd. Dr. Alan Race. It was shot in one sequence. It depicts Smith at a funeral in the church standing in front of the deceased's coffin, then a flashback reveals that Smith actually married the man in question in the same church. The video then returns to the present day, some time after the funeral, with Smith mourning the loss of his husband in the empty church. Critics have pointed out the similarities between this and Guns N' Roses's music video to "November Rain".
