A Tale of the House of the Wolfings and All the Kindreds of the Mark is a fantasy novel by William Morris, perhaps the first modern fantasy writer to unite an imaginary world with the element of the supernatural, and thus the precursor of much of present-day fantasy literature. It was first published in hardcover by Reeves and Turner in 1889. Its importance in the history of fantasy literature was recognized by its republication by the Newcastle Publishing Company as the sixteenth volume of the celebrated Newcastle Forgotten Fantasy Library in April, 1978.

This work and its successor, The Roots of the Mountains, were to some degree historical novels, with little or no magic. Morris would go on to develop the new genre established in this work in such later fantasies as Child Christopher and Goldilind the Fair, The Wood Beyond the World, The Well at the World's End, and The Water of the Wondrous Isles.
