Saint-Sauveur-en-Puisaye is a commune in the north-central French department of Yonne. It is located in an area historically known as Puisaye.
In the early 1970s the Château de la Folie, north of the village was home to one of the "Maharishi's Science of Creative Intelligence" projects.
Transcendental Meditation teachers and students from all over the world gathered here to renovate the buildings and make the château a meditation centre.
