The 2019 Extreme Rules was the 11th annual Extreme Rules professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was held for wrestlers from the promotion's Raw, SmackDown, and 205 Live brand divisions. The event took place on July 14, 2019, at the Wells Fargo Center in Philadelphia, Pennsylvania. The concept of Extreme Rules is that the event features various hardcore-based matches.

Thirteen matches were contested at the event, including two on the Kickoff pre-show. Only three of the main card's matches were contested under a hardcore stipulation. In an impromptu main event, Brock Lesnar cashed in his Money in the Bank contract on Seth Rollins to win Raw's Universal Championship for a record third time, right after Rollins and Raw Women's Champion Becky Lynch had retained their respective titles against Baron Corbin and Lacey Evans in a Last Chance Winners Take All Extreme Rules mixed tag team match. In other prominent matches, Kofi Kingston retained SmackDown's WWE Championship against Samoa Joe, AJ Styles defeated Ricochet to win Raw's United States Championship for a third time, The New Day's Big E and Xavier Woods defeated Heavy Machinery (Otis and Tucker) and defending champions Daniel Bryan and Rowan to win the SmackDown Tag Team Championship for a record-tying fourth-time, and in the opening bout, The Undertaker and Roman Reigns defeated Shane McMahon and Drew McIntyre in a No Holds Barred tag team match, which proved to be The Undertaker's final match in front of a live audience in the United States before his retirement in 2020.
