Clarion is a six-week workshop for new and aspiring science fiction and fantasy writers. Originally an outgrowth of Damon Knight and Kate Wilhelm's Milford Writers' Conference, held at their home in Milford, Pennsylvania, USA, it was founded in 1968 by Robin Scott Wilson at Clarion State College in Pennsylvania. Knight and Wilhelm were among the first teachers at the workshop. In 1972 the workshop moved to Michigan State University. In 2006, the Clarion Writers Workshop moved from Michigan State University to the University of California at San Diego, ironically putting it as far west as the Clarion West Writers Workshop.
Clarion moved - effective 2007 - to the University of California, San Diego. The Clarion Foundation is responsible for the move.
Clarion South Writers Workshop is held in Brisbane Australia. It was founded in 2004. It currently runs biennially. In 2009, Clarion South lost its venue. Although the workshop was held that year, the organizers have had difficulty finding a new home for the workshop. In March 2011, they announced that future Clarion South workshops were "on hold indefinitely."
