Ballad of the Broken Seas is an album released by Isobel Campbell and the first collaboration between her and Mark Lanegan. It made the shortlist for the 2006 Mercury Music Prize.

The Mercury nomination provoked some criticism, as collaborator Mark Lanegan is American and the award is for British and Irish artists only. However Campbell wrote most of the tracks and self-produced the album. Campbell had written the music and some of the lyrics, before sending it to Lanegan. He then agreed to the collaboration and wrote more lyrics. It was not until the actual recording that the two met.
