Tortoise is a perzine by Sue Jones, published in Shrewsbury, Shropshire, UK.
The first issue of Tortoise was released in August 1998. As of Spring 2006, 22 issues had appeared.
Although Tortoise is a perzine, it circulates within the science fiction fanzine community. Each issue is themed. Included are articles, a large letters column, and of course art work, since Sue Jones is an artist.
