Pwyll Pen Annwn (pronounced [pʊi̯ɬ]) is a prominent figure in Welsh mythology and literature, the lord of Dyfed, husband of Rhiannon and father of the hero Pryderi. With a name meaning "wisdom", he is the eponymous hero of Pwyll Pendefig Dyfed, the first branch of the Four Branches of the Mabinogi, and also appears briefly as a member of Arthur's court in the medieval tale Culhwch ac Olwen. Pwyll, Prince of Dyfed also carries many similarities to the Mabinogi Branwen.
