Duchy of Friedland (Czech: Frýdlantské vévodství, German: Herzogtum Friedland) was a de facto sovereign duchy in Bohemia. It was created in 1627 and disappeared in 1634 after death of the ruler Albrecht von Wallenstein (1582 - 1634). It was preceded by the Principality of Friedland (Czech: Frýdlantské knížectví, German: Fürstentum Friedland), which existed from 1624 to 1627.
