The 1992 SummerSlam was the fifth annual SummerSlam professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE). It took place on Saturday, August 29, 1992, at Wembley Stadium in London, England and aired on tape delay on Monday, August 31, 1992. It was the first major WWF pay-per-view to take place outside North America.

The pay-per-view included two main event matches. In the first, The Ultimate Warrior challenged "Macho Man" Randy Savage for the WWF Championship. The Ultimate Warrior won the match by countout but did not win the title. In the other main event, "British Bulldog" Davey Boy Smith pinned Bret Hart to win the WWF Intercontinental Heavyweight Championship. The undercard also included The Natural Disasters retaining the WWF Tag Team Championship against the Beverly Brothers and Shawn Michaels and Rick Martel wrestling to a double countout in a match with the stipulation that the wrestlers were banned from hitting each other in the face.

The event had an attendance of 78,927. WWE themselves claimed a disputed attendance of 80,355, which would make it their seventh-biggest event. Between ticket prices and merchandise sales, the WWF made over $3,650,000 in revenue. Reviews of the event are almost all positive, with the Smith–Hart match rated as the best match in SummerSlam history.

On April 29, 2022, it was announced that a 30th anniversary DVD and Blu-ray would be released for the United Kingdom and European markets to celebrate the anniversary of the event on August 29, exactly 30 years to the event taking place. The release would also include all live event dark matches for the first time which are not a part of the WWE Network showing or on the previous release. During a WWE Live event at London's O2 Arena that same day, it was announced that WWE would return to the United Kingdom to host another major stadium event titled Clash at the Castle in September 2022.
