Jean-Pierre Gury (23 January 1801 in Mailleroncourt, Haute-Saône – 18 April 1866 in Mercour, Haute Loire) was a French Jesuit moral theologian.
He is accounted one of the restorers of the old casuistic method, a fact that made him worthy of personifying the "Jesuit Moral" in the eyes of some, who, especially in Germany, attacked his doctrine.
An ardent follower of Hermann Busenbaum and of Alphonsus Ligouri, he contributed largely towards the final defeat of Jansenism.
