Guillaume de Berghes or of Glymes(1551–1609), baron of Grimbergen, was bishop of Antwerp from 1597 to 1601 and archbishop of Cambrai from 1601 until his death.

After studying Law and Theology at the universities of Louvain, Douai, Dole, Padua and Bologna, Berghes was appointed a canon of the church of St John the Evangelist, Liège.

On 8 April 1578 the prince-bishop of Liège, Gerard of Grœsbeek, appointed him dean of the chapter of St John the Evangelist, after a contested election.

On 5 January 1583 he was transferred to a canonry of Saint Lambert's Cathedral, Liège, and shortly afterwards was sent to Rome as the envoy of Ernest of Bavaria.

[1] By his will he established a bursary of 100 Brabant florins to support a German-speaking student in the seminary of Liège who would serve in one of the German-language parishes of the diocese.
