John II, Count of Blois

John II (c. 1342 – 19 May 1381) was a Franco-Dutch nobleman who ruled lands in both France and the Holy Roman Empire.

John made his chief residence at Schoonhoven, where he patronized French and Dutch poets.

He was proclaimed duke of Guelders by the faction of Heeckerens [nl], supported by the bishop of Utrecht, Arnold of Horne.

That same year, he succeeded his elder brother, Louis III, in the counties of Blois and Dunois.

John spent most of the rest of his life trying to seize Guelders from Matilda's nephew, William VII of Jülich, in the First War of the Guelderian Succession.
