WWE SummerSlam, also promoted as SummerSlam: New Jersey, is an ongoing professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It is the 38th annual SummerSlam and takes place as a two-night event on Saturday, August 2, and Sunday, August 3, 2025, at MetLife Stadium in East Rutherford, New Jersey, and is being held for wrestlers from the promotion's Raw and SmackDown brand divisions. Rapper Cardi B serves as the hostess of the event.

This marks the first SummerSlam to take place across two nights, which was previously only reserved for WrestleMania since 2020. This is the first SummerSlam to broadcast on Netflix in most international markets after the WWE Network merged under the platform in January 2025 in those areas. This is the third WWE event to be held at MetLife Stadium, after WrestleMania 29 and WrestleMania 35 in 2013 and 2019, respectively. This is the fourth Summerslam to take place in East Rutherford after the 1989, 1997, and 2007 events. The event will also feature John Cena's last appearance at a SummerSlam as an in-ring performer due to his retirement from professional wrestling at the end of 2025.
