Riot Fest is an annual three-day punk rock music festival based in Chicago, Illinois, at Douglass Park. It is known for booking reunions, guest performances, and full album performances. Riot Fest remains one of the largest independently owned music festivals in the United States.
 Riot Fest was established in Chicago in 2005 by Mike Petryshyn and Sean McKeough, the latter who also co-produced Chicago's Motoblot annual motorcycle rally. Riot Fest spent seven years as a multi-venue festival, using the Metro, Subterranean, Double Door, Cobra Lounge and the Congress Theater to present bands over a three-day weekend, such as Social Distortion, Danzig, Cock Sparrer, Weezer, Alkaline Trio, the Mighty Mighty Bosstones, Bad Brains, the Dead Milkmen, Fun., the Lawrence Arms, Bad Religion, the Murder City Devils, Butthole Surfers, the Suicide Machines, and more.
 Punk, rock, indie rock, alternative, psychobilly, metal, skate punk and ska are represented at Riot Fest along with reunion sets from Naked Raygun, Wax, Blue Meanies, Articles of Faith, Plow United, the Jesus and Mary Chain, Chiodos, Misfits, Jawbreaker and the Replacements.
 In 2012, Riot Fest moved from various venues around the city to an outdoor venue at Chicago's Humboldt Park and was marketed as Riot Fest & Carnival, with rides, games, wrestling, and food vendors. 2012 also saw the festival expand through North America with events staged in Brooklyn, Toronto, Dallas, and Denver soon after. Since the death of McKeough in 2016, Riot Fest has remained a once-a-year event in Chicago.
 The festival played a key role in the reunions of Naked Raygun, The Replacements in 2013, the Misfits in 2016, and Jawbreaker in 2017, among others.

 In September 2014 Riot Festival & Carnival returned to Humboldt Park for the last time. Roberto Maldonado, who had been a supporter of Riot Fest in the past, stated he would not have the fest back for 2015. This was due to damages to the park after heavy rain during the festival. The repairs cost $150,000.
 Riot Fest 2014 included the inaugural "Riot Fest Speaks" panel, moderated by Henry Rollins and featuring Pussy Riot members Nadya Tolokonnikova and Masha Alyokhina, Bad Religion vocalist and UCLA professor Greg Graffin, Rise Against vocalist Tim McIlrath, writer/activist Marcelle Karp, and Riot Fest founder Michael Petryshyn.

 Conflicts over the condition of the grass and negative effects on the Boricua community, including gentrification of Humboldt Park and lack of financial benefits to the residents of the area led to the festival being moved to Douglas Park. After settling on the new location, Saint Anthony Hospital filed a lawsuit against Riot Fest on September 4, arguing that the festival would be detrimental to their patients' health because of the "extreme noise" and the heavy traffic that would surround the hospital. The two sides reached an agreement which included "restoring parking on 19th Street in front of Saint Anthony Hospital, building pedestrian barricades on the west side of California Avenue and sound monitoring within the hospital to protect patients."

 On March 17, 2017, Riot Fest announced that the festival would not return to Denver, citing the death of co-founder Sean Mckeough the previous November as making it impossible to focus on more than one event in 2017.

 Three instances of Riot Fest have been canceled over the course of the festival's run.
 The first came in 2009 in the form of Riot Fest West, originally set to happen in November 2009 and postponed in September. The fest initially vowed to make up the dates in spring 2010 but the replacement fest did not materialize.
 The second cancellation came in 2012 when Riot Fest East in Philadelphia was again postponed, this time one week before the show's planned July 19 start date. Though a reschedule was initially promised a follow-up never emerged.
 The third cancellation came in 2020 when concerns due to the COVID-19 pandemic made the festival's cancellation inevitable. Organizers have called this a postponement, as a significant part of the 2020 lineup played in the 2021 festival.
 Though not an outright cancellation, Riot Fest Brooklyn in 2012 was shut down early due to weather concerns.
 In 2023, residents of the Douglas Park neighborhood where Riot Fest had been held since 2015 protested the festival's plans to continue operating there. Discussions deteriorated into yelling at a community event between neighborhood residents and festival organizers, as community members complained that the music fest forces them out of large sections of the public park for weeks at a time so private events can be held, damages the park and has displaced youth sports teams that have had to find homes elsewhere. Community members had previously petitioned the Chicago Park District to remove Riot Fest and other music festivals from Douglass Park in 2022.
