The Rundelstone of Oz is a novel by Eloise Jarvis McGraw. It is a volume in the series of fictional works about the Land of Oz, by L. Frank Baum and his successors. The Rundelstone of Oz was originally the opening section of McGraw's The Forbidden Fountain of Oz. Extracted from that book, the Rundelstone story remained unpublished until it was included in the sixth and final issue of Oz-story Magazine, the annual periodical issued by David Maxine and Eric Shanower from 1995 to 2000. The novel was then published in a hardback edition the next year.
