1551, from Mod.L. Utopia, lit. "nowhere," coined by Thomas More (and used as title of his book, 1516, about an imaginary island enjoying perfect legal, social, and political systems), from Gk. ou "not" + topos "place." Extended to "any perfect place," 1613. Utopian originally meant "having no known location" (1609); sense of "impossibly visionary, ideal" is from 1621; as a noun meaning "visionary idealist" it is first recorded c.1873 (earlier in this sense was utopiast, 1854).
