The Duchy of Kuyavia (Polish: Księstwo kujawskie; Latin: Ducatus Cuiaviensis) was a district principality in Central Europe, created in the course of the 13th century in the region of modern-day Kuyavia after the inheritance of the Kingdom of Poland in 1138 into partial duchies through the will and testament of Duke Bolesław III Wrymouth.
