Geoffroy Morin (died 1189) was Marshal of the Knights Templar during the mastership of Gerard of Ridefort.
The date of his departure for the Holy Land and his entry into the Order of the Temple are unknown.
[1] Then he was appointed Marshal of the Order by Gerard of Ridefort, probably in 1188 after the release of the Master of the Order, taken prisoner by the Muslims during the Battle of Hattin.
[2] In 1189, he took part in the Siege of Acre, where he died alongside Gerard of Ridefort and eighteen other Templars.
According to a contemporary poem, he died carrying the Baucent.
