WWE Bad Blood (originally stylized as Badd Blood) is a professional wrestling event produced by WWE, a Connecticut-based professional wrestling promotion. The event was first held in October 1997 when the promotion was still called the World Wrestling Federation (WWF) and that first event was held as the 18th In Your House pay-per-view (PPV) event. After six years and after the promotion had been renamed to World Wrestling Entertainment (WWE), Bad Blood returned as its own PPV event in June 2003, replacing King of the Ring. In 2005, One Night Stand replaced Bad Blood; Vengeance had also moved to June that year as The Great American Bash moved to July. Bad Blood had been announced to be revived in 2017; however, these plans were scrapped in favor of an event titled Great Balls of Fire. After a 20-year hiatus, Bad Blood returned in October 2024, and became the first Bad Blood to air on WWE's livestreaming platforms.

The first Bad Blood is known for introducing the Hell in a Cell match, a 20-foot high roofed cell structure that surrounds the ring and ringside area. It has been contested at every Bad Blood with the match headlining the events in 1997, 2003, and 2004. To coincide with the first brand extension, the 2003 and 2004 Bad Blood events were both held exclusively for wrestlers of the Raw brand division. The brand split ended in 2011 but it returned in 2016. Since April 2018, all of WWE's main roster PPV and livestreaming events have featured wrestlers from both the Raw and SmackDown brands.
