Ultimate Alien Anthology is a supplement to the Star Wars Roleplaying Game published by Wizards of the Coast. It was written by Eric Cagle, Cory J. Herndon, Michael Mikaelian, Steve Miller, Owen K.C. Stephens, and J.D. Wiker, and was first published on April 19, 2003.
The book provides information on 180 species from throughout the Star Wars saga, drawn from sources both well-known and obscure. Each species is also shown along side three other species to show appearance and comparison in size to others. A web enhancement named Ultimate Alien Anthology Web Enhancement was later released, describing two additional species.
