Forbidden Door (2025)

The 2025 Forbidden Door, also promoted as Forbidden Door: London, was a professional wrestling pay-per-view (PPV) event and supershow co-produced by American promotion All Elite Wrestling (AEW) and Japan-based New Japan Pro-Wrestling (NJPW). It was the fourth annual Forbidden Door event and took place on August 24, 2025, at The O2 Arena in London, England, during the United Kingdom's August Bank Holiday weekend, which traditionally hosts AEW's All In at London's Wembley Stadium.

This was the first Forbidden Door held outside North America and the first to take place in August, after the first three events which took place in June. Forbidden Door featured wrestlers from NJPW's sister promotion World Wonder Ring Stardom, Mexican partner promotion Consejo Mundial de Lucha Libre (CMLL), and British partner promotion Revolution Pro Wrestling (RevPro). The event broke the attendance record for a professional wrestling event at the O2 Arena, with an announced attendance of 18,992.

Thirteen matches took place on the card, including four on the Zero-Hour pre-show. In the main event, Darby Allin, Hiroshi Tanahashi, Will Ospreay, and Golden Lovers (Kenny Omega and Kota Ibushi) defeated Gabe Kidd, Death Riders (Jon Moxley and Claudio Castagnoli), and The Young Bucks (Matt Jackson and Nick Jackson) in a Lights Out Steel Cage match. In other prominent matches, "Hangman" Adam Page defeated MJF to retain the AEW World Championship, Zack Sabre Jr. defeated Nigel McGuiness to retain the IWGP World Heavyweight Championship, "Timeless" Toni Storm defeated Athena to retain the AEW Women's World Championship, and Kazuchika Okada defeated Swerve Strickland to retain the AEW Unified Championship. The event was also notable for the returns of Jamie Hayter and Wardlow.
