Dear Diary, My Teen Angst Has a Bodycount is the debut studio album by American post-hardcore band From First to Last. It was released on June 28, 2004, through Epitaph Records. The album peaked at number 12 on the US Top Heatseekers chart and number 21 on the Top Independent Albums.
The title was taken from a monologue in the film Heathers, in which Winona Ryder's character is writing in her diary. Production was handled by Lee Dyess and the band themselves. The album was remastered by Beau Burchell from Saosin, however, it is not indicated on the personnel, possibly due to a contemporary feud between the band.
Dear Diary... is considered to be a "scene album" by some publications, such as Alternative Press. The genres are post-hardcore, emo and screamo. The album also incorporates elements of heavy metal, such as double kick drumming. Vocalist Sonny Moore incorporates clean singing, while guitarist Travis Richter and bassist Jon Weisberg incorporate screaming. Some of the material has drawn comparisons to blink-182. The track "Kiss Me, I'm Contagious" incorporates dual vocals. The track "Emily" is an acoustic ballad. The album's "emo lyrics" explore themes such as heartbreak, angst, self-pity and anger.
The album received generally mixed reviews from music critics. It reached number 12 and 21 on the Billboard Heatseekers Albums and Independent Albums chart.

The hidden track (commonly referred to as "Dead Baby Kickball") features contributing vocals from American rapper Major League Playa.
