Gauscelin de Jean (died 3 August 1348) was a French cardinal.
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 17 December 1316 created him cardinal-priest of SS.
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.
He took part also in the process for the controversy in the Order of the Friars Minor (Franciscans) concerning the poverty of Christ and the Apostles.
