Saeftinghe or Saaftinge was a town in the southwest Netherlands, located in eastern Zeeuws-Vlaanderen, near Nieuw-Namen. It existed until 1584. It is now a swamp known as the Drowned Land of Saeftinghe (Verdronken land van Saeftinghe) and an official nature reserve area. The land is a crosspoint where the river Scheldt meets the salty waters of the North Sea in the estuary Western Scheldt.
