The House of Griffin or Griffin dynasty was a dynasty ruling the Duchy of Pomerania from the 12th century until 1637. The name "Griffins" was used by the dynasty after the 15th century and had been taken from the ducal coat of arms. Duke Wartislaw I was the first historical ruler of the Duchy of Pomerania and the founder of the Griffin dynasty. The most prominent Griffin was Eric of Pomerania, who became king of the Kalmar Union in 1397, thus ruling Denmark, Sweden and Norway. The last Griffin duke of Pomerania was Bogislaw XIV, who died during the Thirty Years' War, which led to the division of Pomerania between Brandenburg-Prussia and Sweden. Duchess Anna von Croy, daughter of Duke Bogislaw XIII and the last Griffin, died in 1660.

The Duchy of Pomerania was a duchy in Pomerania on the southern coast of the Baltic Sea, ruled by dukes of the House of Pomerania (Griffins). The country existed in the Middle Ages between years 1121–1160, 1264–1295, 1478–1531, and 1625–1637.
