Caroline Stanhope, Countess of Harrington was a British socialite and demimondaine. Through her father, she was a great-granddaughter of Charles II. After being blackballed by the English social group The Female Coterie, she founded The New Female Coterie, a social club of courtesans and "fallen women" that met in a brothel. Known for her infidelity and bisexuality, she was nicknamed the "Stable Yard Messalina" due to her adulterous lifestyle. Her "colourful" life is often contrasted with that of her daughter-in-law, Jane Stanhope, Countess of Harrington, who was viewed as a respectable member of British high society.
