Good Mourning is the fourth studio album by American punk rock band Alkaline Trio, released May 13, 2003 on Vagrant Records.

"[1] Recording sessions were held at Cello Studios with producers Joe McGrath and Jerry Finn.

The album marks the first appearance of drummer Derek Grant, described by vocalist/guitarist Matt Skiba as "a whole new influence.

"[2] During recording, both Skiba and vocalist/bassist Dan Andriano were ill.[2] Alkaline Trio had planned a tour with One Man Army in early 2003,[3] but the tour was cancelled due to Skiba having strained vocal chords; the album's recording was subsequently delayed.

[5] Skiba describes the album as sounding "bigger, deeper and rawer" than its predecessor, From Here to Infirmary.

[11] On February 11, Good Mourning was announced for release in three months' time; alongside this, the album's track listing was posted online.

[12] Between April and June 2003, the band toured across the US and Canada, with One Man Army, Pretty Girls Make Graves, and Avoid One Thing.

[15] The UK version of the album included two bonus tracks: "Dead End Road" and "Old School Reasons".
