Tri Martolod or Tri Martolod Yaouank, is a traditional Breton song which dates to the 18th century in Lower Brittany. It was made famous by the interpretation, the arrangement and the recordings made by the Breton harpist Alan Stivell, in the 1970s.

Since the early 1970s, Brittany has experienced a tremendous revival of its folk music. Along with flourishing traditional forms such as the bombard-biniou pair and fest-noz ensembles incorporating other additional instruments, it has also branched out into numerous subgenres.
