Empyr is a French English-language rock band established in 2007 and made up of five members of four different French bands, Kyo, Pleymo, Watcha, and Vegastar.

In 2008, the band released its debut album The Peaceful Riot that was recorded in Los Angeles and produced by Ken Andrews.

The album, which combined elements of Kyo's pop rock with the other members' alternative metal backgrounds, was relatively successful reaching number 17 in France and number 20 in Belgian French charts.

The band has also released a follow-up EP Your Skin, My Skin in 2009, and the album Unicorn in 2011, moving further into the pop rock sound of Kyo on the latter release.

The band has been inactive since 2012, with Poher and Dubos returning to Kyo, while Julliard would eventually rejoin Pleymo, and Duquesne would join industrial metal group Mass Hysteria.
