"Plastic Love" is a song by the Japanese singer Mariya Takeuchi from her 1984 album Variety. Written by Takeuchi and arranged by Tatsuro Yamashita, the song was released as the album's third single on March 25, 1985. "Plastic Love" is a city pop song; its upbeat arrangement contrasts with melancholic lyrics that describe a woman who embraces a hollow, hedonistic lifestyle after being scorned by a lover. Upon its initial release as a single, the song was a moderate success in Japan, peaking at number 86 on the Oricon Singles Chart and selling around 10,000 copies.
