Jülich-Cleves-Berg is the name of two territories across the modern German state of North Rhine-Westphalia and the modern Dutch province of Gelderland.

From 1521 to 1666, the territory is a combination of states in personal union, all reichsfrei territories of the Holy Roman Empire.

The name will be resurrected after the Congress of Vienna for a short-lived province of the Kingdom of Prussia between 1815 and 1822.
