"A Forest" is a song by the English alternative rock band The Cure. Co-produced by Mike Hedges and The Cure's Robert Smith, it was released as a single from the band's second album Seventeen Seconds in April 1980. It was their debut entry on the United Kingdom chart, where it reached number 31. The accompanying music video was first shown on BBC's Top of the Pops programme on 24 April 1980.
Recorded and mixed over seven days, along with the rest of the songs from the album, "A Forest" is representative of The Cure's early 1980s gothic rock phase. The song has featured on the band's setlists for many years. Several versions have appeared on concert albums, and it was remixed and released as a single from the Mixed Up album in 1990. The song has been covered by several artists including Blank & Jones, Sophie Barker and Ror-Shak.
