Arthur Claud Spencer Chichester, 4th Baron Templemore (12 September 1880 – 2 October 1953), was a British soldier and politician of Anglo-Irish descent.

From his father's second marriage, he had a younger half-brother, Sir Gerald Chichester, a diplomat and courtier who served as Private Secretary to Queen Mary.

[6] By now a captain, Chichester distinguished himself in the First World War with his service in France and Italy, becoming a major with the Irish Guards and winning, along with several other awards, the DSO (1918) and an OBE (1919).

[6] In 1924, he succeeded his father as Baron Templemore, and three years later was appointed Parliamentary Private Secretary to the Earl of Onslow as Under-Secretary of State for War and Paymaster General.

His second son succeeded him in the barony and in 1975 inherited the title of Marquess of Donegall in the Peerage of Ireland from a distant cousin.
