Bitterness the Star is the first studio album and debut major label album by the Alaskan metalcore band 36 Crazyfists. It was released on April 2, 2002 through Roadrunner Records, and was produced by Eddie Wohl. "Slit Wrist Theory" was released as a single and is often censored to "Wrist Theory" on music channels. This is the only 36 Crazyfists album to bear a Parental Advisory sticker. It is also Brock Lindow's favourite 36 Crazyfists album; he claimed in the Kerrang! magazine in 2007, "Bitterness will always remain my favourite album, no matter what".
Carl Severson from Nora appears on "One More Word" and Steev Esquivel from Skinlab appears on "Bury Me Where I Fall" as guest vocalists.
