WWE Great Balls of Fire was a professional wrestling pay-per-view (PPV) event and WWE Network event produced by WWE for the Raw brand. It took place on July 9, 2017 at the American Airlines Center in Dallas, Texas.
The event's title referenced a Jerry Lee Lewis song of the same name, which was ultimately used as the event's theme song. Jerry Lawler stated that his personal attorney, who also represents Lewis, had asked him about pursuing legal action over the title, but that he "called them and got everything worked out", including securing rights to use the song itself as part of the event. The name received negative criticism on social media.
Nine matches were contested at the event, including one on the pre-show. In the main event, Brock Lesnar defeated Samoa Joe to retain the Universal Championship. On the undercard, Braun Strowman defeated Roman Reigns in an ambulance match, Bray Wyatt defeated Seth Rollins, and Cesaro and Sheamus retained the Raw Tag Team Championship against The Hardy Boyz in a 30-minute Iron Man match.
