Arthur Annesley, 11th Viscount Valentia, was a British soldier, courtier and Conservative Party politician. He notably served as Comptroller of the Household between 1898 and 1905.

The Comptroller of the Household is an ancient position in the British royal household, nominally the second-ranking member of the Lord Steward's department after the Treasurer of the Household. The Comptroller was an ex officio member of the Board of Green Cloth, until that body was abolished in the reform of local government licensing in 2004. In recent times, a senior government whip has invariably occupied the office. On state occasions the Comptroller carries a white staff of office, as often seen in portraits.
