Plastics, or The Plastics, were a short-lived Japanese new wave music group prominent in the late 1970s and early 1980s. Their music was a major influence on Japanese pop music and their songs have been covered by many bands, most notably Polysics, Pizzicato Five, and Stereo Total.

Perhaps their greatest exposure came from their appearance on the late night comedy show SCTV on NBC performing "Top Secret Man". In September 2007, Rolling Stone Japan rated their debut album Welcome Plastics at No. 19 on their list of the "100 Greatest Japanese Rock Albums of All Time".
