Princess Charlotte Wilhelmine of Saxe-Coburg-Saalfeld (14 June 1685 in Coburg - 5 April 1767 in Hanau) was a German princess by birth and Countess of Hanau-Münzenberg by marriage.
She was the daughter of the John Ernest IV, Duke of Saxe-Coburg-Saalfeld, and his wife, the Duchess Sophie Hedwig of Saxe-Merseburg (1666-1686).
She married Philip Reinhard, Count of Hanau-Münzenberg (1664-1712). She was his second wife and survived him by more than half a century. The dowry that she brought into her marriage was 18000guilders. This marriage, however, remained childless.
After her husband's death, she received Babenhausen Castle as her widow seat. With the death of Johann Reinhard III, Count of Hanau-Lichtenberg, the House of Hanau died out in the male line. The County fell to Hesse and was divided between Hesse-Kassel and Hesse-Darmstadt. She received the stately home Salzhaus in the old city of Hanau, where she lived the rest of her life.
She died on 5 April 1767 at the Salzhaus. She was the last surviving member of the House of Hanau. She was buried on 11 April 1767 in the family crypt in the Lutheran Church (now called the Old St. John's Church) in Hanau. her tomb was largely destroyed when the town was bombed during World War II.
