Philippe Le Portier de Marigny (c. 1260 – December 1316) was the Archbishop of Sens and an important figure in the trials against the Knights Templar during the early 14th century.


Loyal to King Philip IV of France, along with the Assassin Mentor Guillaume de Nogaret and William of Paris, he tortured Grand Master Jacques de Molay, forcing him to admit to heresy.

During the French Revolution, Marigny's descendant, Bertrand Grimany, who used an anagram of the Marigny name as a precaution against those seeking to avenge the Templars, revealed his true heritage to a Parisian newspaper. Shortly afterwards, he was murdered by Anne de Molay, a descendant of Jacques de Molay.
