Critical Wave, later subtitled The European Science Fiction & Fantasy Review, was a British fanzine edited by Steve Green and Martin Tudor between 1987 and 1996. Early editions were mimeographed, with later issues photocopied or - very occasionally - professionally printed.
Contributors included Graham Joyce, Michael Moorcock, Stephen Baxter, D West, Bob Shaw, Steve Sneyd, Charles Stross, Dave Carson, Iain Banks, Jim Porter, David A Hardy, Michael Marrak and Sue Mason.
In 2008, Green and Tudor announced plans to revive the title as an electronic fanzine. The first edition appeared on eFanzines that November, although technical problems delayed the follow-up.
