François de la Chaise (August 25, 1624 – January 20, 1709) was a French Jesuit priest, the father confessor of King Louis XIV of France.
He became a novice of the Society of Jesus before completing his studies at Lyon, where, after taking final vows, he lectured on philosophy to students attracted by his fame from all parts of France.
During the long strife over the temporalities of the Gallican Church between Louis XIV and Innocent XI, Père de la Chaise supported the royal prerogative, though he used his influence at Rome to conciliate the papal authorities.
[1] He exercised a moderating influence on Louis XIV's zeal against the Jansenists, and Saint-Simon, who was opposed to him in most matters, does full justice to his humane and honorable character.
Père de la Chaise had a lasting and unalterable affection for Archbishop Fénelon, which remained unchanged by the papal condemnation of the Maximes.
