Princess Wilhelmine of Prussia (Friederike Sophie Wilhelmine; 3 July 1709 – 14 October 1758) was a princess of the German Kingdom of Prussia (the older sister of Frederick the Great) and composer. She was the eldest daughter of Frederick William I of Prussia and Sophia Dorothea of Hanover, and granddaughter of George I of Great Britain. In 1731, she married Frederick, Margrave of Brandenburg-Bayreuth. The baroque buildings and parks built during her reign shape much of the present appearance of the town of Bayreuth, Germany.
