"Forever" is the debut single by American rock band Haim, taken from their first studio album, Days Are Gone (2013). Released on October 12, 2012, "Forever" was written by band members Alana Haim, Danielle Haim and Este Haim, while production was done by the band with Ludwig Goransson. The song is a pop rock track, with clattering percussion and tight harmonies.

Lyrically, the track talks about a relationship's do-or-die moment, while its sound was compared to many 80's and 90's tracks, including Fleetwood Mac and its member, Stevie Nicks, Donna Lewis and even Michael Jackson's "Wanna Be Startin' Somethin'". Acclaimed by music critics, "Forever" was named a "killer single", with a dazzling chorus, and some even called one of the best singles of the year. The song draws heavily from the themes of the 1979 cult classic film, The Warriors.

"Forever" became the band's first charting single on the charts, reaching moderate positions in Belgium, France, Japan and the United Kingdom, while in the U.S., the song charted in multiple Billboard charts, including the Adult Pop Songs, Alternative Songs, Pop Songs and Rock Songs lists. A music video for the song features the three sisters rocking out in their living room and on their bikes and in a nail salon and all over town, all intercut with videos from their childhood. The song was performed on Jimmy Kimmel Live! and Late Show with David Letterman, as well as at the Glastonbury Festival in both 2013 and 2014.
