Polysics (ポリシックス Porishikkusu? , typeset POLYSICS) is a Japanese new wave and rock band from Tokyo, who dubs its unique style as "technicolor pogo punk". It was named after a brand of synthesizer, the Korg Polysix. The band started in 1997, but got their big break in 1998 at a concert in Tokyo. They create high energy music, fusing conventional guitar music with synthesized and computer generated sound to create a unique mixture of punk and synthpop heavily inspired by the American bands Devo and The Tubes, as well as Japanese bands such as P-Model and Yellow Magic Orchestra.

Their song lyrics often consist of Japanese, English, or just plain gibberish. The band has been noted for their extremely energetic live performances and their wild gimmicky outfits, notably their trademark orange boiler suits, with a simple "P" stamped on them, and their straight-bar sunglasses.
