The 2004 Bad Blood was a professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE). It was the third Bad Blood and took place on June 13, 2004, at the Nationwide Arena in Columbus, Ohio. The event was held exclusively for wrestlers from the promotion's Raw brand division. The following year, Bad Blood was doubly replaced by One Night Stand and Vengeance and would be discontinued until 2024.

The main event was a Hell in a Cell match, in which Triple H defeated Shawn Michaels. Two bouts were featured on the undercard. In respective singles matches, Chris Benoit defeated Kane to retain the World Heavyweight Championship while Randy Orton defeated Shelton Benjamin to retain the WWE Intercontinental Championship.

The event marked the third time the Hell in a Cell format was used by WWE at a Bad Blood event; the first was at Badd Blood: In Your House in 1997 and the second was at the previous year's event. Bad Blood grossed over $494,000 ticket sales from an attendance of 9,000 and received 264,000 pay-per-view buys, and was instrumental in helping WWE increase its pay-per-view revenue by $4.7 million compared to the WWE's previous year. When the event was released on DVD, it peaked at number 3 on Billboard's DVD Sales Chart.
