Arnulf of Chocques (died 1118) was a leading member of the clergy during the First Crusade, being made Latin Patriarch of Jerusalem in 1099 and again from 1112 to 1118. Sometimes referred to as Arnulf of Rœulx, presumably after the village of Rœulx some 70km from his home village of Chocques, he was given the nickname Malecorne, meaning badly tonsured.
