"Writing's on the Wall" is a song by English singer Sam Smith; from the 2015 James Bond film Spectre. The song was released as a digital download on 25 September 2015. The song was written by Smith and Jimmy Napes, and produced by the latter alongside Steve Fitzmaurice and Disclosure and released on 25 September 2015.

"Writing's on the Wall" received mixed reviews, especially when compared to previous Bond theme songs. The mixed reception to the song led to Shirley Bassey trending on Twitter on the day it was released. The single became the first Bond movie theme to reach number one in the UK Singles Chart. It also reached the top 10 in a few other European countries, but unlike other James Bond themes, it was not as successful outside Europe, only peaking at number 43 in Canada and Australia and number 71 on the Billboard Hot 100. Only the instrumental version of the song appeared on the film's official soundtrack album. The song won the Golden Globe Award for Best Original Song at the 73rd Golden Globe Awards and the Academy Award for Best Original Song at the 88th Academy Awards.

"Writing's on the Wall" was co-written by Smith and Jimmy Napes. Smith said that the song came together in one whirlwind session: he and Napes wrote it in under half an hour and quickly recorded a demo. When they listened back to that recording, they were so pleased with Smith's vocal performance that they ended up using it on the final release—albeit with some added muscle in the arrangement. On 8 September 2015 Sam Smith announced that he was singing the song for the James Bond film Spectre. He described performing the theme as "one of the highlights of my career". The English band Radiohead also composed a song for the film, "Spectre", which went unused.
