The 2023 Rebellion was a professional wrestling pay-per-view (PPV) event produced by Impact Wrestling. It took place on April 16, 2023, at the Rebel Entertainment Complex in Toronto, Ontario, Canada. It was the fifth event under the Rebellion chronology.

Ten matches were contested at the event, including two on the pre-show and one taped as a digital exclusive. In the main event, Deonna Purrazzo defeated Jordynne Grace to win the vacant Impact Knockouts World Championship. In other prominent matches, Steve Maclin defeated Kushida to win the vacant Impact World Championship, Trey Miguel defeated Jonathan Gresham and Mike Bailey to retain the Impact X Division Championship, and Team Dreamer (Tommy Dreamer, Bhupinder Gujjar, Frankie Kazarian, Killer Kelly, and Yuya Uemura) defeated Team Bully (Bully Ray, Brian Myers, Kenny King, Masha Slamovich, and Moose) in a 10-wrestler Hardcore War. The event also featured the return of Nick Aldis, announcing his departure from the National Wrestling Alliance (NWA) to sign a contract with Impact.

Rebellion is a professional wrestling event produced by Impact Wrestling. It is annually held during the month of April, and the event was first held in 2019. At Hard To Kill, Impact Wrestling announced Rebellion would take place in on April 16, 2023, at the Rebel Entertainment Complex in Toronto, Ontario, Canada.

The event featured professional wrestling matches that involved different wrestlers from pre-existing scripted feud]s and storylines. Wrestlers portrayed heroes, villains, or less distinguishable characters in scripted events that built tension and culminate in a wrestling match or series of matches. Storylines were produced on Impact's weekly television program.

At No Surrender, Steve Maclin defeated Brian Myers, Heath, and PCO in a four-way match to become number one contender to the Impact World Championship. Later that night, Josh Alexander retained the title over Rich Swann. Impact would later announce that Maclin would challenge Alexander for the title at Rebellion. On March 24, it was announced that Alexander had relinquished the title due to suffering a triceps tear. Maclin would now face Kushida – who was announced to challenge Alexander for the title at Multiverse United – to crown a new champion at Rebellion.

At Sacrifice, Mickie James was originally scheduled to defend the Impact Knockouts World Championship against Jordynne Grace. Prior to Sacrifice, it was announced that James had suffered an injury and would not be able to compete. At the event, James and Impact Director of Authority Santino Marella would have a sit-down interview, with James explaining that she suffered a broken rib and Marella revealing that Grace would get her title match at Rebellion. Additionally, James would not be able to defend her title at Multiverse United against Deonna Purrazzo, Gisele Shaw, and Miyu Yamashita. As such, Masha Slamovich took James' place in the match, with the winner being added to the title match at Rebellion. From there, James would be able to defend the title if she is medically cleared; if not, the title would be held up as vacant and a new champion would be determined in the match. At Multiverse United, Purrazzo won the match to move on to Rebellion. On the April 13 episode of Impact!, James revealed she would not be cleared to wrestle at Rebellion, and was forced to relinquish the Knockouts World Championship. Thus, either Grace and Purrazzo would become the new champion at Rebellion.

At Sacrifice, Bully Ray faced off with former friend-turned-enemy Tommy Dreamer in a Busted Open match. At one point during the match, Dreamer was able to make Ray bleed, but the referee was knocked out beforehand, so he wasn't able to see it. Ray's allies The Good Hands (Jason Hotch and John Skyler) would soon emerge, attacking Dreamer – making him bleed – while also cleaning up Ray's wound. When the referee came to, he saw Dreamer's face covered in blood and declared Ray the winner. After the match, Ray and the Good Hands would continue to assault Dreamer, while putting down rescue attempts from Yuya Uemura and National Hockey League (NHL) legend Darren McCarty, who Ray antagonized in the front row. Impact President Scott D'Amore, who had been away from Impact after being put through a table by Ray, would return and lead a cavalcade of wrestlers – including Heath, Rhino, Jonathan Gresham, Mike Bailey, and Impact Digital Media Champion Joe Hendry – to take out the Good Hands and send Ray running. Needing to settle their feud once and for all, Impact announced that Dreamer and Ray would both lead teams of five in Hardcore War at Rebellion. Dreamer would constantly ask D'Amore to be a part of his team, but due to the latter's new responsibilities, he turned Dreamer down. On the April 6 episode of Impact!, Dreamer, Uemura, and McCarty defeated Ray and The Good Hands in a six-man tag team match. After the match, several more wrestlers, including Frankie Kazarian, Kenny King, Killer Kelly, and Masha Slamovich, would engage in a wild brawl. Later on the full teams were announced for Hardcore War. Team Bully would feature The Good Hands, King, and Slamovich; while Team Dreamer consists of Uemura, Kazarian, Kelly, and later Bhupinder Gujjar. On the April 13 episode, King defeated Kazarian to give Team Bully the person advantage in the match, thanks in part to interference by Brian Myers and Moose. Because of their assistance, Myers and Moose would replace The Good Hands on Team Bully.

At No Surrender, Bullet Club (Ace Austin, Chris Bey, and Kenta) defeated Time Machine (Alex Shelley, Chris Sabin, and Kushida) in a six-man tag team match, with Austin pinning Sabin – who at the time was Impact World Tag Team Champions with Shelley. On the subsequent episode of Impact!, Austin and Bey defeated The Motor City Machine Guns to win the titles. A month later, on the April 6 episode of Impact!, The Motor City Machine Guns challenged Austin and Bey to a rematch, this time an Ultimate X match, at Rebellion, which was made official.
