The Ducal Castle, also known as the Pomeranian Dukes' Castle, and Szczecin Castle, is a renaissance castle in the city of Szczecin, Poland, located at the Castle Hill in the Stare Miasto neighbourhood, near the Oder river. It is built in the gothic and Pomeranian mannerism architectural style. The castle was the seat of the dukes of Pomerania-Stettin of the House of Pomerania, who ruled the Duchy of Pomerania from 1121 to 1637. The building history originates in 1346, when Duke Barnim III began the construction of the ducal housing complex, and continues to 1428, when, under the rule of Casimir V, it was expanded, forming the castle. Currently, it is one of the largest cultural centres in the West Pomeranian Voivodeship, Poland.

Szczecin is the capital and largest city of the West Pomeranian Voivodeship in northwestern Poland. Located near the Baltic Sea and the German border, it is a major seaport and Poland's seventh-largest city. As of 31 December 2022, the population was 391,566.
