A Larum is the debut album of London-based folk rock musician Johnny Flynn, released in the UK on 26 May 2008 and in the US on 29 July 2008.

"[2] In her review for Allmusic, critic Katherine Fullton wrote "it quickly becomes clear that the Wit's intricate, meandering rhythms and melodies are a fitting complement to Flynn's straightforward delivery, augmenting lyrics that would also function as poetry outside of a musical setting...

"[3] Peter Hayward of MusicOMH called the album "a marvellously accomplished and endearing debut that, while rooted in tradition and most easily described as folk, should have broader appeal beyond the beardy-weirdy set.

"[4] Writing for Rolling Stone, David Fricke named A Larum as one of "Fricke's Picks", calling it a "dramatic entrance" for Flynn and his band, drawing allusions between Flynn and earlier folk artists such as Fairport Convention and Bert Jansch.

A Larum was nominated for the Xfm New Music Award (2009) and was also named as the 37th best album of 2008 by Paste Magazine.
