Red Cardell is a French, Breton rock band, that mixes Breton music with rock, folk, blues, world music and chanson réaliste.

The Bretons are an ethnic group native to Brittany, north-western France. They trace their heritage to groups of Brittonic speakers who emigrated from southwestern Great Britain, particularly Cornwall and Devon, mostly during the Anglo-Saxon settlement of Britain. They migrated in waves from the 3rd to 9th century into Armorica, which was subsequently named Brittany after them.
