Oscar Wilde, in one of his less cynical moods, wrote:"A map of the world that does not include Utopia is not worth even glancing at, for it leaves out the one country at which humanity is always landing."
Wikipedia is strangely lacking in its page about Utopian novels

Here is a longer list from the blog, Best Colleges Online.net:

Dozens of other captivating works about Utopia could be added, including The Blythedale Romance (by Nathaniel Hawthorne); Watch the North Wind Rise (by Robert Graves); The Adventures of Mr Marigold (by Michael Tobias); and Thoreau Bound: A Utopian Romance in the Isles of Greece (by Michael Pastore).
We can shape our destinies: we can change our personal lives, we can change the direction of our world. What is the value of these utopian works? ... In addition to being a joy to read, these books expand our imaginations, and give us positive models of societies that are designed so that the first priority is the genuine needs of each individual. A healthy culture supports our lifelong growth and development into creative, caring and compassionate human beings.
