Polyphia is a primarily instrumental progressive rock band based in Plano, Texas, formed in 2010. The group consists of guitarists Tim Henson and Scott LePage, bassist Clay Gober, and drummer Clay Aeschliman.

Polyphia's sound is noted for incorporating virtuosic guitar parts with other styles of music. Initially rooted in a metal-focused tone in their early releases, the band's music evolved to a more progressive rock sound in their later productions, combining electronic music and hip hop. Polyphia has released four studio albums, one live album, two EPs, and numerous singles.

Their third album, New Levels New Devils, was their first to chart, reaching 61 on the Billboard 200. Their fourth album, Remember That You Will Die, released in October 2022, debuted at number 33.
