"Savior" is the eleventh track from Rise Against's 2008 fifth studio album Appeal to Reason. It was released as the album's third single on June 3, 2009, and it peaked at number three on Billboard's Alternative Songs chart, equalling the peak set by the same album's first single, Re-Education (Through Labor), and at number seven on the Rock Songs chart. It became the band's second single to reach the Hot Mainstream Rock Tracks chart, peaking at #16. It is also Rise Against's highest charting single on the Bubbling Under Hot 100 Singles, peaking at #2 (equivalent to #102 on the Hot 100).

The song is available as downloadable, additional content for the Rock Band series along with "Prayer of the Refugee" and "Re-Education (Through Labor)".

On September 8, Rise Against finished shooting a video for "Savior" with director Kevin Kerslake, who directed "Re-Education (Through Labor)", which also appears on Appeal to Reason. It was premiered on MTV2 on September 28. The music video depicts the band playing in a construction site, while numerous people in animal costumes mosh. Inbetween there are scenes of a polar bear riding a bus seeing what looks like animals in homeless situations. Such as a lion going through a dumpster, a tiger lying on a front porch, a group of rabbits standing around a trashcan fire. At the bridge of the song the polar bear sees an elephant limping and stops the bus letting the elephant sit next to them. The two then hold hands when the song ends. According to the director, the song is about forgiveness, and that the elephant represents the Republican Party, and the polar bear is representative of endangered species.

Rise Against later released a slightly different version of the music video, that focused on the band's performance aspects from the original video in which they play and destroy their instruments at the end of the song.
