"All These Things That I've Done" is a song by American rock band the Killers. The song was released as the third single from the band's debut studio album, Hot Fuss (2004), on August 30, 2004. It was written by frontman Brandon Flowers and features gospel choir The Sweet Inspirations. The song is about television host Matt Pinfield, and his work with the US Army, as part of a program that mentored wounded/PTSD-stricken soldiers returning from Iraq.

The Killers are an American rock band formed in Las Vegas in 2001 by Brandon Flowers and Dave Keuning. After going through a number of short-term bass players and drummers in their early days, both Mark Stoermer and Ronnie Vannucci Jr. joined the band in 2002. The band's name is derived from a logo on the bass drum of a fictitious band portrayed in the music video for the New Order song "Crystal".
