The Saturnyns (also known as Saturnynians) are the antagonists of the Doctor Who episode The Vampires of Venice.


They were a race of fish-like aliens who along with their leader Rosanna Calvierri and her son Francesco arrived in 16th century Venice and planned to flood the city to make it their new home and also convert the residents into other Saturnyns to continue their race after their planet Saturnyne was consumed by a crack in the universe. They had the ability to take on human forms but their fangs remained the same, causing people to believe they were vampires.

Their plan was foiled by The Eleventh Doctor and his companions Amy Pond and Rory Williams.
