Rock Anthem for Saving the World is a piece included in the Halo: Original Soundtrack.

It is heard in it's full form on Silent Cartographer just after the Master Chief has activated the map. The initial part of the piece is later heard at the base of the Control Room on the level Assault on the Control Room. It also begins playing when the bottom of the control room is reached on the level Two Betrayals. It is also considered the main theme for the games, although it only appears in this arrangement on the Halo: CE soundtrack. It does reappear in the Halo 2 soundtrack, on the songs Reclaimer and Unyielding.

It runs for 1:20, but is also listed as being 1:17 seconds long, a reference to the Master Chief.
