I Killed the Prom Queen were an Australian metalcore band from Adelaide, formed in 2000. They were prominent in the Australian live music scene and toured the US, Japan and parts of Europe several times. They issued three studio albums: When Goodbye Means Forever... (2003), Music for the Recently Deceased (2006) and Beloved (2014). The latter two albums peaked at #27 and #6 on the ARIA Albums Chart respectively.

The band split up in April 2007 due to the inability to find a permanent vocalist. They reformed with vocalist Michael Crafter to play a farewell tour in mid-2008 and released a live album and DVD, Sleepless Nights and City Lights, which peaked at #48 in Australia. In May 2011 the band reformed with new vocalist Jamie Hope and performed on the Destroy Music Tour. They subsequently released their third studio album Beloved in February 2014.
