François de la Chaise (1624-1709) was a French Jesuit priest and the confessor of King Louis XIV. He is said to have exercised considerable moderating influence over the King, and was widely recognised for his humane and honorable character.
His name became attached to the Jesuit house where he lived. In 1804, Napoleon established a cemetery on the land, naming it the Père Lachaise Cemetery.
It can be found in the 20th arrondissement in Paris.
