Prussian Guelders or Prussian G(u)elderland (Dutch: Pruisisch Gelre; German: Preußisch Geldern) was the part of the Duchy of Guelders ruled by the Kingdom of Prussia from 1713.
The Upper Quarter of the Duchy of Guelders was part of the Spanish-ruled Southern Netherlands by the end of the 17th century.
In the 1713 Treaty of Utrecht during the War of the Spanish Succession, the Upper Quarter was partitioned between the Dutch Republic, Austria, and Prussia.
Prussian Guelders was part of the Lower Rhenish-Westphalian Circle within the Holy Roman Empire.
Prussian Guelders was occupied by Revolutionary France in 1794 and later annexed into the First French Empire as part of the Roer Department.
