Old Crows / Young Cardinals is the fourth studio album from Canadian post-hardcore band Alexisonfire, released on June 23, 2009.

[10] The band announced they would begin recording on February 1, 2009, documenting the process as it happened on their internet blog,[11] with MacNeil stating that "For the first time ever we have too many songs".

[2][14] One week later, Dallas Green announced that the band had already completed seven songs, including "Midnight Regulations",[15] and "probably 8 by the time we finish up".

[11] By March 1, 2009, the band announced in their studio blog that they had "drums, bass and most of the guitars completed", and had "now moved on to leads and overdubs".

[10] Upon returning from Vancouver, further recording took place at Silo Studios in Hamilton, Ontario, the same location used on the band's 2004 album Watch Out!

[27] They co-headlined the Eastpak Antidote Tour, which trekked across Europe, with Anti-Flag; they were supported by the Ghost of a Thousand and the Fall of Troy.

[31] The initial run contains the following French quote across all four sides of the album in the deadwax: Et ses mains ourdiraient/Les entrailles du prêtre/Au défaut d'un cordon/Pour étrangler les rois.

It is a quote from philosopher Denis Diderot's poem Les Éleuthéromanes, translated to: And his hands would plait the priest's entrails, for want of a rope, to strangle kings.
