Four Letter Lie is a post-hardcore band from Minneapolis, Minnesota.
The group formed in 2004 and quickly released an EP entitled Her Escape in May 2005. They followed the release with a heavy tour schedule, which included dates on the Warped Tour and Taste of Chaos tours. The group won an online vote to open the Taste of Chaos date in St. Paul, Minnesota the next year, by which time the group had signed to Victory Records. The group's first record for Victory, Let Your Body Take Over, appeared in October 2006 and was a regional sales success, although it received mixed reviews from press agencies. The group continued touring throughout 2007 and has since written a new album, What a Terrible Thing to Say, which was released on February 19, 2008. The album peaked at #31 on the Billboard Top Heatseekers chart. In spring 2008 Four Letter Lie toured with A Skylit Drive, Oh, Sleeper, and Memphis May Fire and spent the summer touring with Dance Gavin Dance and A Static Lullaby then finished out 2008 with Pierce the Veil, Emarosa and Breathe Carolina.

On 30 March 2009, the band posted a blog on their MySpace announcing that Kevin had departed from the band and is now playing for A Day to Remember.

On 4 July 2009, the band announced via MySpace that their drummer, Derek Smith, had left the band to pursue a rap career with his new band, MOD SUN (Movement On Dreams, Stand Under None. or MODern SUNshine), and that John Waltmann would be switching from bass to guitar.

The band's third album, A New Day, was released on 13 October 2009 through Victory Records. They have done several tours in support of the new release, including a full U.S. run with Love Hate Hero, Sleeping With Sirens, and Of Machines. The band also finished a Canadian tour in April with We Came As Romans and will continue supporting them through May in the U.S. Their headlining tour for their 3rd release, "A New Day", will span across June and July 2010 and will visit both the east and west coasts.
