"Forever Not Yours" is a song by Norwegian synth-pop band A-ha, released as the lead single from their seventh studio album, Lifelines.

The cover of the commercial release features a closeup shot of the black front end of a 1950s Cadillac standing on flatland.

The song's music video, filmed on location in Cuba, was directed by Harald Zwart.

There are many famous faces entering the 'VIP entrance' in this video, including look-a-likes for Desmond Tutu, Madonna, Lenny Kravitz, and Elizabeth II.

In 2017, A-ha appeared on the television series MTV Unplugged and played and recorded acoustic versions of many of their popular songs for the album MTV Unplugged – Summer Solstice in Giske, Norway, including "Forever Not Yours".
