Lucy Sussex (born 1957 in New Zealand) is an author working in fantasy and science fiction, children's and teenage writing, non-fiction and true crime.

In 1979 she attended a Sydney-based Science Fiction Writers' Workshop, conducted by Terry Carr and George Turner and soon after published her first short stories locally and overseas.
