War from a Harlots Mouth is a German metalcore band from Berlin, formed in 2005. Consisting of vocalist Nico Webers, guitarists Simon Hawemann and Daniel Oberländer, bassist Filip Hantusch, and drummer Paul Seidel, the band is noted for a distinct musical style consisting of infusing many different genres into their songs, such as math metal, death metal, and jazz.

The band's first release, an EP titled Falling Upstairs, was released in 2005 exclusively on cassette. Following this, WFAHM released four full-lengths; Transmetropolitan (2007), In Shoals (2009) and MMX (2010). The group's final album Voyeur (2012) was launched just one year before the band's "indefinite hiatus". Their final show took place on 30 December 2013, in Berlin.
