Unforgiven (2004) was a professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE) and presented by Clearasil, which took place on September 12, 2004, at the Rose Garden in Portland, Oregon. It was the sixth annual (seventh overall) Unforgiven event. The show's seven matches showcased prominent WWE wrestlers, who acted out the franchise's stories in and out of the ring. The event starred talent from the Raw brand. It is one of only two WWE pay-per-view events to ever be held in the state of Oregon, the other being No Mercy 2008.

The main event was Randy Orton versus Triple H for the World Heavyweight Championship, which Triple H won by pinfall after executing a Pedigree onto a steel chair. One of the predominant matches on the card was Shawn Michaels versus Kane in a No Disqualification match, which Michaels won after performing Sweet Chin Music. Another primary match on the undercard was Chris Jericho versus Christian in a Ladder match for the vacant WWE Intercontinental Championship, which Jericho won by retrieving the suspended belt.
