Yann ar Floc'h (25 February 1881 – 2 July 1936),[1] pseudonym of Jean Le Page,[2] was a Breton folklorist.

He collected the oral traditions of the Aulne region in the department of Finistère and published them in Breton periodicals.

These texts were posthumously published in the collection Koñchennou eus Bro ar Ster Aon ("Folk-tales from the Aulne river country").

Notably, Yann ar Floc'h collected in 1905 the longest known oral version of the history of King Mark,[5] a version that is of great interest in the study of this character;[6] it blends the legend of Ys, with the premise that Marc was condemned by Gradlon's daughter Ahès [fr] (or Dahut).

[7] These tales form "the original narration of folk traditions"[4] and are representative of the renewal of popular Breton literature in prose at the beginning of the 20th century.
