Sinner is the debut studio album by the American rock band Drowning Pool, released on June 5, 2001, by Wind-up Records.

It is considered to be the band's most popular album, being certified platinum in the same year that it was released.

This is the only studio album by the band to feature original lead singer Dave Williams.

Drowning Pool released a reissue of the album called the "Unlucky 13th Anniversary Edition" in 2014.

[9] Their songs "Mute", "Told You So", and "Reminded" were featured on Dragon Ball Z: Cooler's Revenge.

On "Sermon", Mike Luce stated: "We're fans of the 80s and back in the day there used to be that whole undertone .... oh, if you play that song backwards, you'll hear this message!

[...] It was completely done on a whim and we took a line that Davie (Williams) sang and just ran it in reverse at the tail end of the song.

"[10] The Unlucky 13th Anniversary Edition of the album contains an unreleased demo called "Heroes Sleeping".
