Kingdoms of Elfin is a short story collection by English writer Sylvia Townsend Warner, published by the Viking Press in 1977, a year before her death.

The stories range across various traditional lands of Europe and beyond, including Brocéliande in Brittany, Elfhame in Scotland, Mynydd Preseli in Wales, the Forest of Arden and Bury St Edmunds in England, and as far away as the Peris of Persia.

In a review of The Dictionary of Imaginary Places by Alberto Manguel and Gianni Guadalupi, Naomi Mitchison described Kingdoms of Elfin as "the last and most brilliant of Sylvia Townsend Warner's books".

[2] Thomas M. Disch included Kingdoms of Elfin in his list of "modern classic" works of fantasy.

[3] Darrell Schweitzer described The Kingdoms of Elfin as containing "memorable flashes" and said that the stories "reveal new complexities on rereading".
