Princess Caroline of Denmark (28 October 1793 – 31 March 1881) was the eldest surviving daughter of King Frederick VI of Denmark. She was unofficially known as "Kronprinsesse Caroline" (English: Crown Princess Caroline) prior to her marriage, and later as "Arveprinsesse Caroline" (English: Hereditary Princess Caroline). In 1829, after several failed marriage attempts, she was married to her father's first cousin, Hereditary Prince Ferdinand, who was heir presumptive to the throne from 1848 to 1863.
