Sylvie Denis (born 10 November 1963 in Talence) is a French science fiction writer.

[2] She became interested in science fiction at an early age, first through a television series, then by discovering the books in the Fleuve Noir Anticipation collection.

Her short story L'Anniversaire de Caroline won the Solaris Prize in 1988 and was included in her first collection, Jardins virtuels [fr], in 1995.

[3] In the mid-1990s, she co-founded the magazine Cyberdreams, which won the Grand Prix de l'Imaginaire in 1996, and was sole editor-in-chief for the last two issues.

Her collection Jardins virtuels was republished in 2003 by Gallimard in a much expanded version (thirteen short stories instead of five).
