The Duchy of Brzeg (Polish: Księstwo Brzeskie) or Duchy of Brieg (German: Herzogtum Brieg; Czech: Knížectví břežské) was one of the Duchies of Silesia, created in 1311 during the fragmentation of the Duchy of Legnica. A Bohemian fief from 1329, it was ruled by the Silesian Piasts until their extinction in 1675. Its capital was Brzeg in Lower Silesia.
