The 2005 Vengeance was the fifth annual Vengeance professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE). It was held exclusively for wrestlers from the promotion's Raw brand division. The event took place on June 26, 2005, at the Thomas & Mack Center in Las Vegas, Nevada.

The main event was a Hell in a Cell match for the World Heavyweight Championship between Batista and Triple H, which Batista won by pinfall after executing a Batista Bomb. One of the predominant matches on the card was John Cena versus Chris Jericho versus Christian in a Triple Threat match for the WWE Championship. Cena won the match and retained the title after pinning Christian. Another primary match on the undercard was Kurt Angle versus Shawn Michaels in a rematch of their bout at WrestleMania 21. Michaels won the match by pinfall after executing Sweet Chin Music.

Many of the existing feuds were settled following the event. Notably, Batista was drafted to the SmackDown! brand, thus ending his feud with Triple H. The feud between Kane and Edge also concluded after the event, as Edge entered an angle with Matt Hardy. The feud between Cena and Jericho, however, continued and led to a match at SummerSlam, which Cena won.
