Racetraitor is an American hardcore punk and metal band originally from Chicago, Illinois. The band attracted controversy in the late 1990s, before any releases, as a result of their radical take on racial politics, which focused on ideas like systemic racism and white privilege before they were widely discussed topics in popular or underground culture. Racetraitor was also a key proto-metalcore act, one of the first few bands to incorporate extreme metal influences, such as death metal, grindcore, and doom metal, into hardcore.

In 1998, the band released their album Burn the Idol of the White Messiah. The album was followed by a split EP with Indianapolis band Burn It Down called Make Them Talk in 1999 before an initial breakup. The band has reformed as of 2016 and has since released four new EPs and two LPs, 2042 and Creation and the Timeless Order of Things.

Racetraitor was formed in 1996 by drummer Karl Hlavinka, guitarist Daniel Binaei, bassist Brent Decker, and vocalist Mani Mostofi, playing powerviolence/grindcore music. Early songs were extremely short and heavily filled with noise. The songs were recorded in a demo that was not publicly released until 2016.

In the early shows, Racetraitor took a more confrontational approach to spreading social justice ideas. The band became known for calling their own audience members "crackers", which the band explained as not a racial category but a term for people who perpetuate racism and exploitation in their day-to-day lives. During a performance in Columbus, Ohio during this period, the band members criticized members of Anti-Racist Action for focusing on white nationalist groups like the Ku Klux Klan rather than systemic issues such as institutional racism, leading to a physical altercation between the groups.

Racetraitor's reputation in your face politics spread quickly throughout the hardcore scene resulting in cover stories in both Maximum Rocknroll and Heart Attack zine, two of the biggest punk and hardcore publications of the era, before they had released a single note of music. A readers poll in Hear Attack ranked the band as one of the most loved and hated band of 1996.

A year into the band, Andy Hurley joined as a drummer and Hlavinka began performing as a guitarist. The band noted that when Hurley joined the band, they changed sounds to match his technical ability, shifting from a noisy powerviolence band to a style closer to 1990s death metal. Hlavinka soon quit, only to return to the band on and off over the years. In 1997, the band went into Sonic Iguana studios Lafayette Indiana to record their debut. In 1998, Uprising Records released Burn the Idol of the White Messiah. Decker soon left the group; a number of musicians played bass in the band temporarily, including Fall Out Boy's Pete Wentz.

In 2016, Racetraitor announced via Facebook that a new remixed version of Burn the Idol would be re-released on vinyl. In October 2016, the band played its first show in 17 years with Detroit hardcore band Earthmover. In September 2016, the group released two new songs: "By the Time I Get to Pennsylvania" and "Damaged". Hurley attributed the band's reformation to the current political situation. "We had discussed playing a show or doing something else over the years, but nostalgia was never all that motivating, so the idea died," Hurley explained. "But with everything happening in the past couple of years, from the way things heated up in Ferguson, Missouri, to the rise in xenophobia and bigotry reflected by the popularity of Donald Trump, making new music with Racetraitor felt important again."

In July 2017, British label Carry the Weight Records released a reissue of Burn the Idol of the White Messiah. The record was remixed by Dallas Thomas from Pelican. The same month, Organized Crime Records released the EP Invisible Battles Against Invisible Fortresses. The band supported the record with shows across the US, including the This is Hardcore festival, and a small European tour with Sect, which included a stop at Fluff Fest in the Czech Republic.
