The term "Mabinogion" was invented by Lady Charlotte Guest in the 19th century and refers to her collection of eleven prose narratives taken from a variety of medieval Welsh manuscripts.

Some of the narratives also feature Arthur and may represent source material for the Arthurian legend that is earlier than Geoffrey of Monmouth or Chretien de Troyes.
