"Forever" is a song by American recording artist Chris Brown from Exclusive: Forever Edition, a repackaged edition of his second studio album Exclusive. Brown co-wrote the song with Andre Merritt, Rob Allen, Brian Kennedy, and Jamal "Polow da Don" Jones; the latter two are also the producers. Initially created to be used for Ableton Live practice, "Forever" was selected to be released as the first single from Brown's repackaged second studio album but overall it's the fifth single from the album. It was first released for digital download on November 2, 2007. The song's musical structure differs from Brown's previous work, opting for a more European techno dance sound.

The song reached number one in Ireland and New Zealand as well as peaking within the top ten in Australia, Canada, United Kingdom and United States. It also reached the top forty in countries like Denmark, Germany and Switzerland. The accompanying music video features Brown in several scenes pursuing his love interest. The video features much dancing and digital effects. The official remix features Lil Wayne and Lupe Fiasco.

The song was written by Brown and his songwriting team, the Graffiti Artists (Rob Allen and Andre Merritt). He stated that after entering the studio, Polow da Don created a beat that Brown wrote along to. Because the producer's style was "more of a European, techno, house-type feel," the group "wanted to give it that other side of crossover, and go a little bit to that pop realm". "Forever" is one of four new songs Brown recorded for the re-release of his second studio album Exclusive. He recorded the song using an autotune effect, as he did in one of his previous singles, "Kiss Kiss". The song was first intended to be on Brown's following album, but decided he "wasn't ready to release a new album yet".

"Forever" is actually an extended version of a commercial jingle for Doublemint gum, commissioned by an advertising company working for Wrigley. Brown first created the short version for the commercial, then extended and amended it into a full song during a recording session in February 2007, which was paid for by the gum company. Originally, the plan was to follow up his third single, "With You," with the Kanye West-featuring "Down," but the new material won out. Although the label initially was reluctant to release "Forever" as a single, the song was so "potent and strong" that it overruled any hesitations regarding its commercial connections.
