Princess Frederica Charlotte of Prussia (Friederike Charlotte Ulrike Katharina; 7 May 1767 – 6 August 1820) was a Prussian princess by birth and a British princess by marriage. She was the eldest daughter of King Frederick William II of Prussia and the wife of Prince Frederick, Duke of York and Albany, second son of King George III of the United Kingdom.
