"Orange Trees" is a song by Welsh singer and songwriter Marina from her fourth studio album, Love + Fear (2019). The song was released for digital download and streaming as the album's third single on 22 March 2019 by Atlantic Records. It was written by Marina, Oscar Görres, Erik Hassle, and Jakob Jerlstrom, while produced by Görres. Several remixes of the song were commissioned by Atlantic and released throughout 2019, including one produced by German DJ Claptone. An acoustic version of "Orange Trees" appears on Marina's sixth extended play, Love + Fear (Acoustic) (2019). Musically, the song has been described as an electropop and indie pop track, with a tropical beat and lyrics that describe a summer romance spent in the beauty of nature. Marina wrote the song about the island city of Lefkada, Greece, where her family once lived.

It was released in full on 26 April 2019 by Atlantic Records, though the album's first half was released on 4 April 2019 as a surprise. Diamandis took a hiatus after she concluded touring in support of her third studio album Froot (2015) with plans of retiring from music. However, she began working on a new record with several producers like Sam de Jong, Oscar Görres, Joel Little, Jack Patterson, Mark Ralph, James Flannigan, and Oscar Holter during its recording.
