Geoffroy le Rat (died 1207) was the thirteenth grand master of the Knights Hospitaller, serving between 1206–1207.
[2] Geoffroy le Rat did not occupy the position of Grand Master until mid–1206 and the beginning of the second half of 1207.
He was of French origin, attached to a family of Touraine.
[3] He had been a commander in the Principality of Antioch and lord of the Krak des Chevaliers before being elected as master.
[4] As the Fourth Crusade was diverted to Constantinople, the Hospitallers did not have a military role at the beginning of the thirteenth century.
