The Duchy of Münsterberg-Oels was a historical Silesian principality, ruled by the House of Poděbrady (Podiebrad) from the late 15th century, unifying the separate Duchies of Münsterberg (Ziębice) and Oels (Oleśnica) under one line until the dynasty's extinction in the mid-17th century. It existed within the Kingdom of Bohemia/Holy Roman Empire until Prussian annexation in 1742.
