Colonel Francis Cecil Ricardo, CVO, CBE (3 July 1852 – 17 June 1924) was a British Army officer, police officer, and philanthropist.
Ricardo was born at Bramley Park at Guildford in Surrey, the son of Percy Ricardo and his wife, Matilda Mawdesley, the daughter of John Isaac Hensley of Holborn in Middlesex. He was the brother of both Colonel Horace Ricardo and of Amy Mary, Duchess of Richmond. He was educated at Eton College and followed his older brother, Horace, into the Grenadier Guards in 1872.
He was promoted to captain on 8 June 1884, to major on 10 December 1890, and to lieutenant-colonel on 10 February 1897. In January 1900, he received a staff appointment as an assistant adjutant-general for the Home District, with the temporary rank of colonel whilst so employed. He was later aide-de-camp to the Lord Lieutenant of Ireland, and retired from the Army in 1909.
In 1899 he became honorary secretary of the Naval and Military Tournament and held the post until 1910, when he resigned following a disagreement with the Army Council over some of the content.
During the First World War he served as acting chief constable of Berkshire County Constabulary.
