The Enchanted Island of Oz is a children's novel written by Ruth Plumly Thompson and illustrated by Dick Martin, and first published in 1976. As its title indicates, the book is an entry in the series of Oz books created by L. Frank Baum and his successors. It is the last (and shortest) of Thompson's 21 novels about the Land of Oz. The original edition of the book contains maps of the fantasy territories drawn by Martin and James Haff, and an afterword by Dorothy C. Maryott.
