Unique was a science fiction fanzine by Arthur Williams published in London, England.
Williams had previously published The Science Fantasy Fan in 1941, but had fell ill and needed to abandon his publication while in the hospital. Upon his recovery, he resumed publishing in 1942 with the new title, Unique.
Issue two, published in 1942, consisted of a cover drawn by Williams, a prolific fan artist for fanzines such as Futurian War Digest, an editorial, poetry, and articles by Joe Gilbert (The Southern Star), R.W. Lowndes, J.E. Rennison, and Duane W. Rimel.
At least three issue of Unique appeared.
