Princess Augusta of Hesse-Kassel (Augusta Wilhelmina Louisa; 25 July 1797 – 6 April 1889) was the wife of Prince Adolphus, Duke of Cambridge, the tenth-born child, and seventh son, of George III of the United Kingdom and Charlotte of Mecklenburg-Strelitz.
In 1803, her uncle's title was raised to Elector of Hesse—whereby the entire Kassel branch of the Hesse dynasty gained an upward notch in hierarchy.
On 7 May, in Kassel, and then, again, on 1 June 1818 at Buckingham Palace, Princess Augusta married her second cousin, the Duke of Cambridge, when she was 20 and he 44.
In 1827 Augusta allowed that a new village, founded on 3 May 1827 and to be settled in the course of the cultivation and colonisation of the moorlands in the south of Bremervörde, would bear her name.
On 19 June the administration of the Hanoveran High-Bailiwick of Stade informed the villagers that she had approved the chosen name Augustendorf for their municipality (since 1974 it is a component locality of Gnarrenburg).
