Marianne von der Leyen und zu Hohengeroldseck (1746–1804), was a German noblewoman from an ancient House of Leyen, who served as regent of the County of Hohengeroldseck.
Marianne married Count Franz Georg Karl Anton von der Leyen und zu Hohengeroldseck (1736-1775).
After the death of her husband, she was regent of the County of Hohengeroldseck during the minority of her son Philip Francis, Prince of Leyen from 1775 to 1793.
[1] As the age of legal majority was twenty-five, she legally ruled until 1791, but as her son showed no interest to take over the affairs of state, she was able to continue her regency until the invasion and occupation of Revolutionary France in 1793.
After the French invasion, she managed to escape from the county dressed as a maid servant.
