"Invisible Sun" is a song by British rock band the Police, released as a single in Europe in September 1981.

You can't always see it, but there has to be something radiating light into our lives.The song's lyrics stem from songwriter Sting's pondering how people living in war-torn and/or impoverished countries find the will to go on living, and despite the dark music and often morbid lyrical statements, the song carries an uplifting and optimistic message.

And the Lebanese must have been feeling some heat from the invisible sun, because they were keeping their peckers up.Bono performed duets of it with Sting when U2 and the Police appeared at the same concerts: the first such instance was in 1982 at a festival in Gateshead, England, and two subsequent instances occurred at the last two shows of Amnesty International's A Conspiracy of Hope Tour in 1986.

Among other things, the lyrics refer to the ArmaLite rifle used by paramilitary organisations, but mainly by the Provisional Irish Republican Army.

The song was revised as a duet between Sting and vocalist Tony "Gad" Robinson with an upbeat tempo and a prominent horn section.
