Unique was a science fiction fanzine by Arthur Williams published in London, England.
Williams had previously published The Science Fantasy Fan in early 1941, but had fell ill and needed to abandon his publication while in the hospital. Upon his recovery, he resumed publishing later in the year with the new title, Unique.
Issue one, from October 1941, included contributions by Paul Dennis Lavond, Robert Lowndes, and Duane w. Rimel, with cover and interior art by Williams.
Issue two, published in December 1941, consisted of a cover drawn by Williams, an editorial, and articles by Joe Gilbert (The Southern Star), R.W. Lowndes, John Edward Rennison, and Duane W. Rimel, and poetry by W. Robert Gibson.
Four issues of Unique appeared in the 1940s, with the fifth issue retitled as Trends.
