Austin Tappan Wright (August 20, 1883 – September 18, 1931) was an American legal scholar and author, best remembered for his major work of Utopian fiction, Islandia.

From 1908 to 1916 Wright worked for the law firm of Brandeis, Dunbar and Nutter in Boston, after which he taught at the School of Jurisprudence at the University of California, Berkeley from 1916 to 1924.

Although Wright's professional colleagues were aware he had literary interests outside his field and some anticipated he might eventually branch out into other areas of literature, these possibilities appeared precluded by his early death.

Few people outside Wright's own family knew he had long been working on an extensive Utopian fantasy about an imaginary country he called Islandia, with an elaborately worked-out history, culture and geography, comparable in scope to J. R. R. Tolkien's life-long writings of Middle-earth.

In his papers he left a 2300-page manuscript of a novel exploring the country, with appendices including a glossary of the Islandian language, population tables, a historic peerage, and a gazetteer and history of each of its provinces.

After Wright's death his widow typed and edited the manuscript for publication, and following her own death in 1937 their daughter Sylvia further edited and cut the text; the novel Islandia, shorn of Wright's appendices, was finally published in 1942, along with a promotional pamphlet by Basil Davenport, An introduction to Islandia; its history, customs, laws, language, and geography, based on the original supplementary material.
