Ultrawarp was a media science fiction fanzine devoted published by the Victoria based fan club Time-Trekkers.
Published in the 1990s in Bendigo, Victoria, Australia, Ultrawarp was devoted to Star Trek and Dr. Who.
Editors have included Simon Mead.
In his February 1998 review, David J. Richardson said, "First up, the short trip north to find the Time-Trekkers and 28th edition of their Ultrawarp. As ose names suggest, they cover a stack of sci-fil and related things...It's got a more newsletter than zine feel, but well worth it."
Ultrawarp is included in the Susan Smith-Clarke Zine Collection at The National Library of Australia.
