The Song of Rhiannon is a fantasy novel by American writer Evangeline Walton, the third in a series of four based on the Welsh Mabinogion. It was first published in paperback by Ballantine Books as the fifty-first volume of the Ballantine Adult Fantasy series in August, 1972. It has been reprinted a number of times since, and gathered together with Walton's other Mabinogion novels by Overlook Press as the omnibus The Mabinogion Tetralogy in 2002. The novel has also been published in translation in several European languages. The other three novels in the series are The Island of the Mighty (1936), The Children of Llyr (1971), and Prince of Annwn (1974).

The novel is a retelling of the story of the Third Branch of the Mabinogion, Manawydan Fab Llŷr (Manawyddan, son of Llŷr).
