Érard de la Marck^[1] (French pronunciation: [eʁaʁ də la maʁk]; 31 May 1472 – 18 March 1538) was prince-bishop of Liège from 1506 till 1538.^[2] He was born in Sedan, Ardennes, the third son of Robert I de la Marck [fr], lord of Sedan and Bouillon.

Érard was also lord of Jametz, bishop of Chartres (1507–1525) and archbishop of Valencia (1520–1538). He was nominated Cardinal in 1520.^[2] He first tried to obtain protection from the King of France and finally allied with the emperor. He succeeded in securing peace in the prince-bishopric during his whole reign.

His reign is considered as the most flourishing of the Bishopric of Liège. He reconstructed the prince-bishop's palace, ruined by the wars of the last century with Burgundy. He also restored many monuments, including Saint Martin collegiate church.
