Phantastes: A Faerie Romance for Men and Women is a fantasy novel written by George MacDonald. The story centers on the character Anodos and takes its inspiration from German Romanticism, particularly Novalis. It concerns a young man who is pulled into a dreamlike world and over there he hunts for his ideal of female beauty, embodied by the "Marble Lady". Anodos lives through many adventures and temptations while in the other world, until he is finally ready to give up his ideals.

George MacDonald (1824-1905) was a Scottish author, poet, and Christian minister. He was a pioneering figure in the field of fantasy literature and the mentor of fellow writer Lewis Carroll. His writings have been cited as a major literary influence by many notable authors including W. H. Auden, C. S. Lewis, J. R. R. Tolkien, Walter de la Mare, E. Nesbit and Madeleine L'Engle. G. K. Chesterton cited The Princess and the Goblin as a book that had "made a difference to my whole existence".
