Impending Doom is an American Christian deathcore band from Riverside, California. The group has released six full-length studio albums, and consists of Brook Reeves (vocals), Manny Contreras (guitars), David Sittig (bass) and Andrew Holzbaur (drums). Reeves and Contreras are the only two remaining original members. The band refers to their style as "gorship", a portmanteau of gore and worship.

Guitarist Manny Contreras and vocalist Brook Reeves started Impending Doom on October 31, 2005.

The group signed to Facedown Records in January 2007. Their debut release for the label, Nailed. Dead. Risen., reached number 46 on the Billboard Top Heatseekers chart. The record has received generally positive reviews. The band started a street team to promote their music, which can be found on their Myspace top 8. The group toured the United States to support the album in autumn 2007, including dates with Dead to Fall, Winds of Plague and With Dead Hands Rising.

Impending Doom released their second album, The Serpent Servant, on March 31, 2009, which hit number 3 on the Billboard Top Heatseekers chart.

Baptized in Filth was produced by Andreas Magnusson, who produced Oh, Sleeper's album Children of Fire, and was mixed by Machine. The album focuses on God, Satan and Number of the beast. The first single was "For the Wicked" and the first video was "Murderer". A few months after the release of Baptized in Filth, Cory Johnson was fired from the band and replaced with former founding member Manny Contreras, who had become a member of Oblige (later known as The Devastated) during his time off from Impending Doom. Johnson joined fellow Christian metal band MyChildren MyBride.

Lead vocalist Brook Reeves performed at the Mitch Lucker Memorial Show on December 21, 2012, with Suicide Silence in honor of their deceased vocalist, Mitch Lucker, who died on November 1, 2012. Reeves performed the song "Ending Is the Beginning", off the 2005 Suicide Silence. On February 26, 2013, Reeves was featured on the single "Efforts to Outcomes" by Demise.

The band confirmed that their album Death Will Reign would be released through eOne Music on November 5, 2013.

On July 19, 2022, the band posted on social media that they were working on a follow-up to Hellbent, with Reeves stating they hoped to release it "sooner rather than later."

On November 6, 2023, the band released the song "Eternal", along with the announcement of the EP Last Days, released on November 20, 2023, as their first independent recording.
