Mercury Falling is the fifth studio album released by Sting. The album was marked by its tight studio production and heavy use of synthesizer tracks. This release was considered by many fans to signal the beginning of Sting's transition from heavier jazz-inspired rock to the adult contemporary genre.

The track "Twenty Five to Midnight" is not available on every release of the album. It is listed in the official Sting.com discography tracklist, but it excluded from the USA and Canada releases.

The album begins and ends with the words "mercury falling".
