Caroline von Berlepsch, Countess of Bergen (9 January 1820 – 21 February 1877) was a member of the noble von Berlepsch family and was the third wife of the Elector William II of Hesse-Kassel.
On 28 August 1843, she was married to William II, who was 43 years her senior, in Wilhelmsbad (now part of Hanau).
This was a morganatic marriage, because she was considered lesser nobility and therefore not befitting for a sovereign Elector.
The couple's main residence was Frankfurt, since the elector had in 1830 and virtually abdicated the government to his son, Frederick William I, from his first, non-morganatic, marriage.
After William's death in 1847, she married again, to Count Charles Adolph of Hohenthal (1811–1875) on 28 October 1851 in Frankfurt.
