Dorothea Friederike of Brandenburg-Ansbach (12 August 1676[1] - 13 March 1731) was the daughter of Margrave John Frederick of Brandenburg-Ansbach (1654 - 1686) and his first wife, Margravine Johanna Elisabeth of Baden-Durlach (1651 - 1680). She was a half-sister of Queen Caroline of Great Britain, the wife of King George II.
On 20 (or 30) August 1699, Dorothea Friederike married Count Johann Reinhard III of Hanau-Lichtenberg.[2] She was the last Countess of Hanau. The marriage produced one daughter: Charlotte Christine Magdalene Johanna (1700 - 1726). Charlotte was the sole heiress of the county of Hanau and married on 5 April 1717 Crown Prince Louis VIII of Hesse-Darmstadt (1691 - 1768).
Friederike Dorothea died on 13 March 1731 and was buried on 17 or 25 March 1731[3] in the family vault of the Hanau counts in the St. John's Church (Hanau) (currently known as Old St. John's Church) in Hanau.[4] The tomb was largely destroyed in the bombing of the Second World War.
