Forbidden Door

Forbidden Door is a professional wrestlingpay-per-view (PPV) event co-promoted by the American promotionAll Elite Wrestling (AEW), the Japanese promotions New Japan Pro-Wrestling (NJPW) and World Wonder Ring Stardom, and the Mexican promotion Consejo Mundial de Lucha Libre (CMLL). Established in 2022, it is generally held annually in June, although it was held in August in 2025. The event features direct competition between wrestlers from the promotions involved, and its name came from a term that had often been used by AEW in its early years when working with other professional wrestling companies.

The event was originally only co-promoted between AEW and NJPW. After CMLL and Stardom were featured at the 2024 and 2025 events, both became official co-sponsors in 2026. The 2025 event was the first to take place outside of North America as it was held in London, England and broke the attendance record for a professional wrestling event at The O2 Arena.
