Warmness on the Soul is the first EP by American heavy metal band Avenged Sevenfold. It was released on April 10, 2001, through Good Life Recordings. The release features the video for the title track "Warmness on the Soul" as an enhanced CD bonus. It is the band's first release to feature guitarist Synyster Gates, who joined the band in February 2001. All of the songs were later included on Avenged Sevenfold's debut album, Sounding the Seventh Trumpet, except for the heavy metal version of "To End the Rapture", which was featured on the album's re-release.

Some of the band members' stage names are slightly different compared to their current ones. M. Shadows is simply credited as "Shadows", while Synyster Gates is credited as "Synyster Gaytes".
