Henry Shirley, 3rd Earl Ferrers (14 November 1691– 6 August 1745), known as Hon.
Henry Shirley until 1729, was an English hereditary peer and person who suffered from mental illness.
His mental disorder led his younger brother, Laurence, to obtain a commission of lunacy against him.
However, Ferrers' condition improved and he regained control of his estates in October 1730, the year after he succeeded his elder brother Washington in the earldom.
Lord Ferrers was confined during the last years of his life and died in Kensington Gore in 1745 at the age of 53.
