Gauscelin de Jean (died on August 3, 1348) was a French cardinal. He was born at Cahors in the family related (by the marriage alliance) to the family of Pope John XXII. From 1312 he was archdeacon of Paris. Pope John XXII shortly after his election to the papacy named him Vice-Chancellor of the Holy Roman Church (occupied the post until 1319), and in his first consistory on December 17, 1316 created him cardinal-priest of SS. Marcellino e Pietro. In 1317 together with Cardinal Luca Fieschi unsuccessfully tried to mediate (as papal legate) between Scotland and England. In Scotland the legates were even detained for some time due to their alleged partiality in favour of England. In 1319 Gauscelin was more successful by arranging a truce between France and Flanders.
