"The Unforgiven" is a power ballad by American heavy metal band Metallica. It was released as the second single from their eponymous fifth album Metallica (also known as The Black Album). The song deals with the theme of the struggle of the individual against the efforts of those who would subjugate him.^[1]

The song has since spawned two sequels, in the form of "The Unforgiven II", from the album Reload, and "The Unforgiven III", from the album Death Magnetic.

"The Unforgiven II" was written by James Hetfield, Lars Ulrich and Kirk Hammett and appears on the album Reload as a sequel to "The Unforgiven." Both songs have similar musical themes. The chord progression during the verses is strikingly similar to the one used in the chorus on "The Unforgiven". Hetfield's verse melody is played with a B-Bender guitar; a guitar that allows the player to bend the B string independently of other strings.^[24]

"The Unforgiven II" video is similar to the first video's story, though a tunnel is substituted for the blank room shown in the first video. It begins with a shirtless boy stuck in a wall, showing the wall breaking piece by piece as the boy ages. As the video progresses, it becomes more abstract, with waves crashing on the other side of the wall and rupturing it, making the wall smaller each time. The final scene shows the remaining piece of the wall turning into a woman, with the now older boy's hand still embedded in her back. The boy opens his hand, allowing the woman to take the key out of his hand and allowing him to take his hand out of the wall.^[25]

"The Unforgiven II" was first performed live on December 8, 1997, at that year's Billboard Music Awards. The song was not played in a live setting again for the next 17 years, until Metallica re-introduced it into the setlist for their 2015 European festival tours.^[26] Following its performance in Gelsenkirchen, Germany's Rock Im Revier festival, Metallica then included it in the setlists of their next three shows.^[27]

"The Unforgiven III" appears on the album Death Magnetic, released in 2008. "The Unforgiven III" is structured similarly to "The Unforgiven", containing a heavy verse and a soft chorus, "The Unforgiven II" had the opposite by having a soft verse and a heavy chorus. The chorus of "The Unforgiven III" is missing the "What I've felt, what I've known" phrase that was included in its predecessors' choruses. "The Unforgiven III" is also missing the opening horn note, instead beginning with an acoustic piano with a horn section in the background. The chords progression during the piano intro is the same as the choruses of the previous songs. Unlike its predecessors, "The Unforgiven III" features as the seventh track on Death Magnetic, due to the band wanting "The Day That Never Comes" to be the fourth track after they returned to writing ballads. However, due to the song being the counterpart of "The Day That Never Comes", it is the fourth song from closing the album.^{[citation needed]} This is the first "Unforgiven" not to be released as a single or to have a music video.

In an interview for MTV, James Hetfield said that the song is "continuation of the same storyline about sin and consequence, forgiveness and unforgiveness." Hetfield has also said that, of all parts of "The Unforgiven," this is his favorite.^[56] Robert Trujillo said "it's got a great flow and it's very dynamic. It's somehow connected to the [remaining] body music of the album."^[57]

Stephen Thomas Erlewine from AllMusic in his review of the album, described the song as having "symphonic tension".^[58] A live version was performed for the first time on April 14, 2010, in Oslo, Norway, and only played a few times afterwards with the last performance being on November 21, 2010. It was played for the first time in almost eight years in Lincoln, Nebraska, on September 6, 2018, and was next performed on the two nights of Metallica and the San Francisco Symphony's S&M2 at the Chase Center, albeit in an alternate form featuring only Hetfield and the orchestra.^[59][60] In 2010, it was nominated for the Grammy Award for Best Hard Rock Performance but lost to "War Machine" by AC/DC.^[61]
