The 2025 Slammiversary will be a professional wrestling pay-per-view (PPV) event produced by Total Nonstop Action Wrestling (TNA) that will take place on July 20, 2025, at the UBS Arena in Elmont, New York. It will be the 21st event under the Slammiversary chronology, and celebrate the promotion's 23rd anniversary.
Production.
Background.
Slammiversary is a professional wrestling pay-per-view event produced by Total Nonstop Action Wrestling (TNA) to celebrate the anniversary of the company's first event, which was held on June 19, 2002. As such, the event is usually held in the summer (June or July). The first event took place nearly a year after that event on June 18, 2003, and has since been considered one of Impact's premiere PPV events, along with Bound for Glory and – since 2020 – Hard To Kill, and Rebellion.
On December 4, 2024, it was announced by TNA that Slammiversary would take place on July 20, 2025, at the UBS Arena in Elmont, New York.
Storylines.
The event will feature professional wrestling matches that involve different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portray villains, heroes, or less distinguishable characters in scripted events that build tension and culminate in a wrestling match or series of matches.
At NXT Battleground, Trick Williams defeated Joe Hendry to win the TNA World Championship, marking not only the first time a TNA championship changed hands on a WWE-produced event, but the first time a WWE-contracted wrestler held a TNA championship. Since then, Williams disparaged the legacy of TNA and had vowed to mold the company into his vision, calling it "TrickNA," while making limited appearances. He'd also defend the world title against challengers from both TNA and NXT on "NXT" television, such as Mike Santana and Josh Briggs. However, following the latter defense, Williams was ambushed by Hendry and sent running. Two days later on the June 26 episode of "TNA Impact!", Hendry was delivering a promo to the crowd before being interrupted by TNA Director of Authority Santino Marella, who informed Hendry that would be granted his rematch for the TNA World Championship against Williams at Slammiversary. However, later that night, Santana, after defeating A. J. Francis in a street fight, demanded that he be added to the match, given how in his previous attempt on "NXT", Fir$t Cla$$ (Francis and KC Navarro) had gotten involved. Marella would announce via social media four days later that Santana would be in the world title match at Slammiversary, officially making it a three-way match. 
At Against All Odds, Leon Slater, The Hardys (Jeff Hardy and Matt Hardy), and The Home Town Man faced The System (Brian Myers, Eddie Edwards, JDC, and TNA X Division Champion Moose) in a eight-man tag team match. The former team would ultimately secure the win, with the finish seeing Slater pin Moose, putting him in contention for the X Division title. As such, on the subsequent episode of "TNA Impact!", Santino Marella announced that Moose would defend the title against Slater at Slammiversary.
