Gwerz ({{IPA|br|ɡʷɛ̞ʀz|lang}}, "ballad", "lament", plural {{lang|br|gwerzioù}}) is a type of folk song of Brittany. In Breton music, the {{lang|br|gwerz}} tells a story{{cite book|title=Focus: Irish Traditional Music|author=Sean Williams|publisher=Routledge|isbn=0-415-99146-3|year=2010}} which can be epic, historical, or mythological. The stories are usually of a tragic nature. The gwerz is characterised by an often monotonous melody and many couplets, all in the Breton language. Though historically sung unaccompanied,{{cite web|url=http://denezprigent.tripod.com/bio.html|title=Denez Prigent|accessdate=26 Dec 2013}} some modern musicians use limited instrumentation with the gwerz.

Some of the most famous performers in current gwerzioù are Erik Marchand, Yann-Fañch Kemener, and Denez Prigent.{{citation needed|date=November 2017}}
